Has anybody used RPC before?


Recommended Posts

I use them everyday at work and sometimes up to 1000 of them and never have an issue.

Not sure if it will make a difference or not but we have a server for libary files and rpcs so it frees up the render boxes juice.

Every so often i will get a rpc a bit bright or the something along those lines but not very often

You can enable rpc shadows. Click the "mass edit" button under "RPC Edit Tools". Be warned though, rpcs are 2d objects so you will not get the best results when it comes to shadows. There are some ways to overcome this by faking in shadows. You can make your own shadows by applying a shadow image with an opacity map to a plane placed just above the ground or you can cast shadows from a 3D object that is not visible to the camera. 3DAS had a good example of this in their 2nd tutorial. Here's the link if you are not familiar with their weekly tutorials posted here at cga. http://www.cgarchitect.com/upclose/VI/default.asp

You can also create a shadow projector map

Go to your direct light or sun which ever you are wanting to get a shadow from, hide everything else except what you want to shadow render out a nice big image. Save it as a TGA with a alpha split. Go to photoshop and invert the alpha split so black becomes white and white becomes black (you can delete the none alpha image).

Then put this map in your material editor in a slot that you can leave it there.

Go to the sun or light then modify list then advanced effects. Click on projector map search in your material editor and click the shadow map and make it an intance. Then you make everything that you just created a shadow from not project shadows and there you have it and nice shadow.

This is also great if you have a lot of plants and want to cut down the rendering time as you have turned shadows off on a lot of objects.

Only prob with this is if there is an object thats in the path of the shadow it will project on the object so go to photo shop and delete that shadow.

Which works out fine because if there is an object in the way this means what ever shadow required there will already be shadowed by the object.

 

Not sure how much sense that makes but hope that helps
