Quite interesting bug with Edge mode
« on: October 10, 2016, 11:19:15 AM »
Hello
I've encountered this kind of bug when i am using Edge mode for ForestPack.
It occurs quite random on different models / materials.

As you can see it cuts geometry producing complete transparent alpha.
Is there a solution for this ?
And thing is that from another angle and lighting - this part is completely fine

Hi,

It 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 FAQ 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,
