Forest Pro Black Area's
« on: July 05, 2016, 07:52:11 PM »
Getting random black areas within our render.  We increased the Max density thinking that would fix it but it still appears.  Is it something to do with the amount of forest plants? We are using the latest forest pro.
Any help would be much appreciated

Hi,

That seems to be a similar issue as the "White pixels on Forest grass with edge mode enabled" one:

"Looks like, V-Ray exceeded its default transparency limit (which could cause similar render artefacts). I would suggest you to increase Global switches - Max transp. levels (default value is 50). Sometimes may be necessary to modify Secondary rays bias also.

As mentioned 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)."


Best regards,
