VRay and RPC Shadow Light

Recommended Posts

Here at our office, we have been using RPC for entourage for quite some time, just as many of you have. We upgraded last year to VRay for our production renderer and have fully integrated it into (if not rebuilt around it) our pipeline. We would always end up using the RPC shadow light plug-in to create the shadows for all of our RPC items. Once we upgraded to VRay however, we were struck with a problem. The shadow light would not create the shadow map (.jpg) using VRay.

 

After messing around with it more, we were able to figure out a workaround for this. By using the scanline renderer and a standard 3ds light, we could create the image, and then work it back into our VRay based file, and create our final image, which would then include all the shadows for our content. This was all done in Max 8 and now 9.

 

We are now looking to upgrade to 2009, and the latest RPC plug-ins. However, we are unsure as to whether or not this is possible anymore. On RPC's own site, it specifically states that it is NOT compatible with most 3rd party rendering engines, including Mentalray. We contacted Archvision, and were told that the shadow light not only will not work in any fashion with '09, but it has apparently never been able to be used with a 3rd party renderer.

 

Obviously we found this odd, since we had been doing it for just over a year. So my question is this... have any of you been able to use the RPC shadow light plug-in (in any way shape or form), in a 3rd party renderer, to create shadow maps (OR use the scanline created maps)?

i am having the same issues! this is the reason i am waiting to install 2009, as i have just started using the shadow plugin. i also use vray, and have had no luck with it. so im rendering my rpc's separately, and rendering them with scanline, with a shadow matte material applied to everything else.

 

cursed RPC's!

Hello, i have the same problem with final render and rpc shadowlight...

 

I am using 3dsmax 9 with RPC Shadow plugins v1.1.2... i render the shadow map with scanline and after i render my scene with fR .

I have tested RPC Shadow plugins.v1.2.80 but the shadow maps is not used ... so i have to stay with the 1.1.2 version ...Please Archivision can you correct this problem ...

a quick solution may be to select the rpcs and rightclick, change pruoerties and enable cast shadows n receive shadows. this works best for rpcs than are 3d in nature, not the billboard flat types. then under modifier panel, switch off shadows from rpc to avoid double shadows. mas recognisis the rpcs as oblects, and cast shadows based on the 3d mesh nature. i tried it and it works just okay.....unless my newbieness is really starting to show..lol
