It would be great if VRED offered a feature that allows scattering objects (as instances) across a base surface using customizable parameters. A common use case would be distributing vegetation within environment scenes. A nice example of this can be seen in D5 (D5 Scatter Tool). The following capabilities would be especially helpful for configuring scattering.   Selection of the Scatter Objects Choose a single object or a collection of objects (e.g. from an asset library) Distribution Methods Scatter across the entire selected geometry Scatter within specific sub‑areas (of the geometry): Place objects by clicking directly on the base surface Brush‑based distribution with adjustable brush size Distribution along splines Use of color maps to define sub‑areas, enabling different objects or collections based on color regions Distribution Details (depending on the placement method) Density: Objects per unit area, optionally controlled by a density map Weighting: Probability of occurrence for each object within a collection Distance: Minimum/maximum spacing between objects, optionally using collision volumes Region settings (region size, blur, etc.): For the “entire geometry” method, regions can be generated randomly based on size and frequency (e.g., Region 1 with Object A, Region 2 with Object B) Smooth transitions between regions adjustable via blur parameters Alignment: Align objects to surface normals or keep alignment independent Offset: Vertical offset of all scattered objects from the base surface Collisions: Options for handling collisions with other scene objects Variation Random scale values (min/max) per axis or uniform scaling Optional position jittering (min/max) per axis Random rotation values (min/max) per axis Seed value to control the overall randomness of the scattering variation Show More

Since VRED 2026.1 its (finally) possible to reset the DLSS history!   We added Python commands for setting the DLSS phase count to a higher accumulation phase count and reset DLSS history. Now, when switching variants, the colors of the two variants won't mix and result in an incorrect result, instead the DLSS accumulation history is reset. setDLSSMaxPhaseCount(framecount) - Sets the number of frames DLSS renders before going idle. The minimum frame count is 72. getDLSSMaxPhaseCount() - Returns the max phase count. resetDLSSHistory() - Resets the DLSS accumulation history and starts over. Calling this function might be necessary when switching color variants, in order to get the correct colors and reduce artifacts due to the accumulation history. For example, setDLSSMaxPhaseCount(279) print getDLSSMaxPhaseCount() Source:  VRED 2026 Help | General Improvements | Autodesk (Section "Scripting")   API Documentation:  VRED 2026 Help | vrOSGWidget | Autodesk   That's really useful when DLSS is active and an immediate change between one material and another is neccessary. Without the use of vrOSGWidget.resetDLSSHistory, the appearance of the previous variant gets blended into the next. Example: Switching from a blue car paint to a red car paint will be visualized in purple colors and might stay a little bit purple, even when sampling stops.   But how do you expect us to use this feature?   Add it to all VariantSet scripts that might change the appearance like that? vSetScriptToAdd = """# VRED 2026.1 feature resetDLSSHistory() # Resets the DLSS accumulation history and starts over. # Calling this function might be necessary when switching color variants, # in order to get the correct colors and reduce artifacts due to the accumulation history. # https://help.autodesk.com/view/VREDPRODUCTS/2026/ENU/?guid=general-vred-20261 if float(vrController.getVredVersion()) >= 18.1: resetDLSSHistory() else: vrLogWarning(f"VRED {getVredDisplayVersionYear()} doesn't support vrOSGWidget.resetDLSSHistory().

""" vSets = [getVariantSet(vSetName) for vSetName in getVariantSets()] for vSet in vSets: vSetScript = vSet.getScript() if not vSetScriptToAdd in vSetScript: vSet.addScript(vSetScript + "\n\n" + vSetScriptToAdd) vrLogInfo(f"Script added to VariantSet '{vSet.getName()}'") Result:   Suggestion 1: Unfortunately, there's no API v2 signal (at least none that I'm familiar with) that I can connect to when VariantSets are switched. Please provide... an API v2 version of the vrVariantSetPtr class  an API v2 service (e.g. vrVariantSetService) with capabilities similar to vrVariantSets, but with signals that we can connect to   Suggestion 2: And enable us to use 'resetDLSSHistory()' with each activated VariantSet (when DLSS is active) with a setting in the VRED preferences   Suggestion 3: ...ask the community for feedback and ideas! I'm just one person without Autodesk's knowledge and might have ****ty suggestions 😁   Sidenote: The class vrVariantSetPtr doesn't have the getters/setters we need and lacks so many features. Example: How to use the 'sequential animation' checkbox? 🙄 Export (all) variants with vrVariantSets.saveVariants(name) Manipulate (temporary) xml file on disk with python Re-Import manipulated XML with vrVariantSets.loadVariants(name) Delete temporary xml file    Show More

When using the Skylight function to create a timelapse, it would be great to have a sky full of stars when it's night. It would also be great to be able to add simple volumetric clouds from the skylight menu.   Lastly, the ability to have them move with the time of day would be super helpful. Show More

When making a change to a variant set - currently, you need to go through the Sets one by one to make a change.   Let's say you need to change a geometry switch, and that switch is present in a Variant Group, and the Group has 100 Variant Sets in it. Currently, you need to manually go into each Set and manually adjust the switch.   It would be great if you could bulk select the whole group, and make a change to a specific line item/switch and have it update to any selected Set.   Currently, this functionality works in Cameras where you bulk select a viewports in a camera and then make a change and it be applied to all selected cameras - it would be a huge time save if this was available for Variant Sets.

As subject line says - the ability to add a bump or displacement map to a shadow material would be a great feature - allowing for the illusion of a ground where there isn't one. Show More

Hello,    We have a use case where we have multiple variant sets. Within Each there are multiple Material Switches. Each Switch has 100+ materials (yes I know thats crazy). When we are trying to create a new V-Set for each vehicle configuration we have to use the very poor Drop Down menu in the V-Set Editor to select the material.    Would really like to be able to update the V-Set currently active from the Material Editor. If there could be just a RMB Drop Down Menu -> 'Apply to Current Variant Set'     This would simplify things a bunch.   Thanks   N Show More

It would be great to have the ability to bake materials for export to other DCC's. Especially multipass materials, for example:   In this case this is a MultiPass material containing two separate materials, after baking, the red "decal material" and green "base material" will be flattened into a single output for each channel respectively (Diffuse/Roughness/Normal etc). The baking process should also generate textures based on the current UV maps or have the option to automatically do a quick unwrap for the objects. Show More

The current process requires the user to select all the parts to be included in the light group, but this would be a cumbersome task if you have an assembly of parts and need to exclude only a few from that assembly. An exclude function would allow for the user to just add the excluded parts to that "exclude" group. While still maintaining the "include" group. Show More

Hi   I have a python script which basically controls the clippingplane with a controller i.e by using getpinchstrength So i have a box or an object which i pinch to get hold of it and move it to control the clippinplane. This all works fine but since the clippingplane clips or cuts all objects along its path the controller box is also getting clipped.   Would be great if there is a way to exclude certain objects from the clipping plane i.e to tell the clipping plane not to clip some objects   Thanks Show More

when you start haveing a lot of measurements in the file it is kinda difficult to highlight one among the others or recognize it when you have more than one overlapping.   imho some options might be added to the measuring window such as: assign colors highlight selected one hide\show single measurements option offset ...

It would be useful to be able to identify the channel by simply select the keyframe from the curve editor. Best Riccardo Show More

VDB and cameras do not have any option to hide their icon in the viewport in Open GL. There are workarounds for both of them but it would be great if there was a single-click solution to turn off all icons, tripods, navigation cubes, etc. from the viewport. Best Riccardo Show More

At the current time it is impossible to make a rusty metal shader based on textures in Vred, unless we import a substance material, but this requires having a substance license as well. The problem is that the plastic shader does not have any metalness channel.  It would be great if there was an universal shader that would support also metallic input channel. Best Riccardo.

The shadows produced by the lights in open GL can be softened through the shadow map filter slider in the light menù, however this softness does not match the softness that can be seen in raytracing, this makes it not very user friendly to pass from open GL to ray tracing or for baking lights.   It would be fantastic if there was an optional option that could be activated to automatically match the softness of the shadows in Open GL based on the size and distance of the light. In this way, point, spot, and directional lights would always be sharp shadows also in open GL, while area lights would have a softness related to their size.   Also it would be useful to have a way to control the softness of the directional light in raytracing as well, at the moment is always sharp. The warkaround that I'm using now is to put a very very far spherical light in place of the directional light and change its size and intensity at needs, but it is very inconvenient.   Best, Riccardo Show More

It would be useful to be able to turn on and off multiple selected elements from the scene graph. at the moment even if I select multiple objects when I click on the tick to turn them on and off it turns on and off only one element at a time. Show More

Hello,   I'm aware of the possibility of exporting a spherical environment to be used as a reflection probe to simulate reflections in Open GL, however, with this method it is not possible to simulate realistic reflections of an object on a glossy floor for example. I suggest adding the support to planar reflection probes or screen space reflections that can run on low-performance machines as well. best, Riccardo. Show More

when you isolate a geometry or a node, this does not affect lights. in particular, if you have area lights in your scene, they all become visible, even the one hidden or nested in switches.   this is annoying in particular when you have multiple lights simulating displays Show More

V 2025 is a great update! It can handle USDZ files, which is a huge relief when juggling assets between DCCs. I know, VRED is not built for this but how great it would be if it had a scatter function to play with. Smart referencing and cloning are already in place, the only thing missing is a scatter tool like V-Ray Scatter or similar. Is anything in the pipeline?   Thanks, Z Show More
