Crash with particles and deformer displacement on a plane

Unread postby Vincent » Thu Jun 08, 2017 2:13 pm

Hello,

Clarisse 3.5 crashes when I want to change the spans of a plane which has a displacement in the deformer input. Combined with a point_cloud and scatterer set on collision. If I disable the point_cloud and scatterer I can change the span of the plane without crashing. But if I turn the point_cloud back on it will crash again. I hope this can be solved quickly or an idea with some work around. Thanks you in advanced.

Cheers,
Vincent

Hi,

Thanks for the report. We haven't reproduced your problem for the moment. Could you send us a simple project ?

Hi,

I dived more into the problem and the crash happens when I turn on a 4K sample texture map in the particle node. Can you add that to your reproduced test? My plane is set to 800,800. If that don't reproduce the crash I will send you an example but it will take some time.

So what I have now, A Clarisse plane with 800x800 spans with a deformer displacement. PointCloud (50000 points) with a sampling texture (4K). Than a scatter node with collision detection and a simple sphere as a scatter object. The scatter node has several geometry's alembics that scatters onto the plane.

Thanks
Vincent

Hi Vincent

The crash your're mentioning is probably fixed in the next release candidate. It seems that the source of the issue is the sampling texture of the point cloud combined with a deformed geometry. We managed to reproduce your crash on the first release candidate with a simple grid deformed having a lot of spans, and it seems to be ok since our latest fixes on the point cloud sampling texture.

Could you please warn us if you don't crash anymore with the next release candidate (coming soon) ?

Thanks for your feedback

Actually you can already download it! The fix is available on 3.5 RC2

Thanks
