bug splat with displacement

[david_87]

hi all! i have a the same bug splat every now and then, whenever i try to render a big file (about 15 to 20mb) with displacement (grass), it ends up crashing and closes, any idea how to fix that? thank u

Re: bug splat with displacement

Hmmm it's very difficult to know because there is more than one reason that can cause the crash.
The most common causes of crashes that i've experienced was due lack of Ram memory.
Btw 20mb file isn't considered large (imho)

Hope someone will give you better answer than mine.

Best luck.

Re: bug splat with displacement

Displacement needs to be calculated on a per face basis. Chances are if you're using grass, then you've placed the displacement material on a very large plane. This means that V-Ray will have to calculate the displacement for half (the plane is split into 2 triangles ) of the plane at a time. This means that the displaced mesh will require a significant amount of memory in order to calculate that mesh, and is most likely at the cause of your crash. Make the plane out of smaller faces and you probably won't see this issue.

Re: bug splat with displacement

You'll need to slice up the plane or make a smaller one then extrude the edges to make it bigger.
