Is edge mode not supported for VrayProxy / Render Elements
« on: January 29, 2016, 10:15:56 AM »
Hello,

we are wondering if there is a problem using edge mode with vrayproxies instead of meshes.

We are using Max2016+Vray3.20.03, and experience that edge mode seems to be ignored when using vrayproxies.

Is this a known issue? If it is, it would be nice to mention it in the documentation.

Another thing we noticed is, that using edge mode the geometry is only correctly cut away in diffuse, while the render elements show artifacts/ghosting.

Thanks
Christian

Hi Christian,

Please accept my apologies, edge mode isn't compatible with V-Ray Proxies, we'll update the documentation to reflect this.

If the render elements show artefacts it could be that V-Ray has exceeded its default transparency limit. Often increasing Global switches - Max transp. levels (default value is 50) will resolve this. Sometimes may be necessary to modify Secondary rays bias as well.

You'll find more information in this "Some key notes about Areas->Boundary Checking->Edge mode" related post: "In the case of very high density scatters (like dense grass), many overlapping objects could be generated and V-Ray may exceed its default transparency limit (which can cause render artifacts)". You can find there how to fix it (use lower Density values / increase VRay's Max transp. levels).

I hope that helps.

Many thanks!

Paul
