Gobo with Arnold does not support GPU

[MichaelDavidRocha]

I am trying to use the GPU to render as much as possible to speed up my workflow and  I am doing several long scenes in a forest using the AIGobo to project leaves.  However, it would appear the AiGobo does is not support when rendering with GPU. So I am doing software render. 

Does anyone have any ideas for a workaround to get this effect and get my render back on GPU?

Hi!

Light filter aiGobo is supported with GPU render mode and the latest version of Arnold.

Here it works.

I do not understand your answer. Here are 2 renders, one with CPU and one with GPU. The Gobo indicates it is not GPU driven and you can see that in the output.

Hello,

I encountered the same issue and I upgraded to Arnold 6.0.2.0.

Unfortunately, after trying to do a gpu render (with aiGobo) my render does not show the light filter and get the warning:

"// Warning: [gpu] unable to link parameter "slidemap" of node "aiGobo2", failed to compile shader for source node"

I would like to know if there is a solution.

Thank you for reading

What do you have connected to slidemap?

An image node works.

But thank you for your answer, an image works so it is easy to achieve the same effect by creating an image file.
