What help is there for ACA 2010/2011? Cant find anything other than a brief AU handout (AB310-3). The results I got were rubbish - materials are all there, some basic light ray casting, have no problems with cameras etc. Then rendering out as jpegs its horrible blotchy, low resolution, nasty lines and blotches, no definition of shade. Also have tried sliding in a background sky and landscape but cant figure out how to position and get a sensible relation to the 3D.
What I want is comprehensive book or tutorial. Cant find much in the ACA Help. Lookup online training and it takes you to Autocad 3d rendering. Mental Ray is embedded in the product but with nothing I can find to tell you how to use it.
Here is a typical approach that I might use to genreate a renderingm after I have all of the geometry and materials in place, etc.: (And in this walk-thru, I am referring specifically to an exterior redering.)
1. Make sure that I am in a perspective view. You can use a camera, as you mentioned, or when in a 3D orbit, right click and choose perspective. (Or there are probably 4 other ways to do this as well.) BEING IN PERSPECTIVE AFFECTS YOUR ABILITY TO USE THE SUN AND SKY.
2. Go to the Render tab.
3. Under the render tool, under the render tab, you can pull-down pre-set settings, from Draft to Presentation. These are pretty reliable to get started.
4. Under the little Render arrow, you can further refine. But that is for another time.
5. Two important things to do: Turn on the sun (click the big sun icon an inch to your right) and turn Sky and BackGround illumination on. This will give the the ambient lighting and soft shadows of the sky vault.
This should get you started.
If you are still getting blotchy, click on the tiny arrow that says Render: Increase your image output size, as well as the render quality )1-5 scale.
When you really want to do a final draft, there is one setting that I feel is critical. You can click on the microscopic arrow, next to the word Render that is pointing down and to the right, OR you can type in RPREF, for advanved render settings. Look for FINAL GATHER, and turn it on. This will use a good bit more memory, and take longer, but will make for a nicer final output.
Oh, and click the Teapot Render button!
Hope this helps. Hit me with any specific questions.
find the arch-desktop.customer-gallery for some images of what 2009 can do.
I think it's much better than VR as you don't have to swap programes to
render and model.
Find a mistake? Just fix it and re-render. No need for all that links
I have just started learning the updates in 2010/11 and it supposedly has
improved but I am yet to prove that. Hopefully a service pack will take
care of the bugs!
2011, the materials interface has been updated and it does seem the
rendering has improved. (bump)
One essential factor I didnt state is I dont use the ribbon as it really slows workflow! As I see now much of the functionality is not there on toolbars and so didnt get anywhere. Not a problem as I did set a custom Ribbon workspace so can switch quite quickly.
Followed you guide and printed the output onto photo paper. Nice shaddows, brick texture etc at 1024x768. Next I want a bit of terrain and landscape.
Any tips on bringing in sky and some background landscape. With VIZ I could slide a photo of the real background in and size and position this fairly realistically (would be ADT 2006 last time).
Then just paint the resultant solid with the grass or whatever you like. You may want to right-click and convert it to a 3d solid. These seem to 'paint' better.
I typicall don't put backgrounds in AUTOCAD. But I think is done via you camera. Just type "V" for view. Near the lower part of the dialogue box is a pull-down for background, where you can choose an image, or whatever.
For LANDSCAPE I highly recommend downloading the free RPC plugin from ARCHVISION. (RPC= Rich Photorealistic Content.) Google it. I can tell you more about this later. You can download several sample RPC's that are pretty cool. If you are a subsrciption ACAD user, Archvision will give you a library of somehting like 100 RPC's!!! This is a big deal. You can completlely landscape your scene beautifully with these.
FYI unfortunately using a background is not compatible with 'Sky & Illumination' which is necessry to get your shadows softer. You can take the image into a phtoo editor that is capable of colour selecting the sky and replaing it with a sky map afterward.
The drape command gives you a MassElemet which to add materials needs a material & render material assigned.
You could convert it to a solid but the ME has some flexibility for editing that might be valuable.
Also look at the model explorer which can contain the original terrain model and the cuts and fills as + & - elements.
Do you know all about the Roof Object? Learn it's secrets
Tried Archvision standalone and then found the subscription install. That works fine. But cant get a sucessful install of the ACA plugin for 2011 - it "installs" but no folder created - should be a cuix file but none. Have done the same for 2010 which is fine but the cuix doesnt read in 2011. So there is a possible issue with the plugin for ACA 2011. Havent tried migrating the 2010 cuix.
Using the CUI command I went in to C:\WhereYouInstalledIt\RPC\Plugin\RPCcui and loaded the rpc2010.cuix file and now the commands work. Haven't got the license to work yet though.

Archvision RPC 2011 now working OK - a restart and the ribbon menu and toolbar now installed to the workspace.
Wow doesnt it work well! Looks like once placed the rpc objects cant be rotated or moved in xyz.
You should be able to move an RPC just like a block. No big deal.
I think the two tricks to RPC's are
1) Make sure that you differentiate between stills and RPC's for 3D. I did an animation using stills, and all of the trees and such would flip suddenly when I passed by them.
2) When you get done placing all of the RPC's go to the MASS EDITOR on the RPC tab. Select all of the RPC's in the list and make sure that they "cast shadows" and "cast reflections". I don't know why, but some of them come in without these automatically turned on. Can't imagine why.
But you should be able to move, copy, rotate, etc. with no problem. Hmmm . . .
