About the SnippetPBF Case，added a Prism but Visualization Is Not Working Properly

[123uiui]

Here is the code I added to this case, and it threw the exception shown in the image below.

static float randomVertices7[20][3] = { { 0.875709, 0.000000, 0.000000 }, { 0.734122, 0.000000, 0.533371 }, { 0.313272, 0.000000, 0.964153 }, { -0.328454, 0.000000, 1.010877 }, { -0.863303, 0.000000, 0.627226 }, { -1.047619, 0.000000, 0.000000 }, { -0.836285, 0.000000, -0.607597 }, { -0.367963, 0.000000, -1.132475 }, { 0.338421, 0.000000, -1.041554 }, { 0.683973, 0.000000, -0.496935 }, { 0.836693, 0.1, 0.000000 }, { 0.799592, 0.1, 0.580938 }, { 0.314927, 0.1, 0.969246 }, { -0.297332, 0.1, 0.915093 }, { -0.693421, 0.1, 0.503800 }, { -0.851336, 0.1, 0.000000 }, { -0.796614, 0.1, -0.578774 }, { -0.309294, 0.1, -0.951908 }, { 0.307749, 0.1, -0.947155 }, { 0.869869, 0.1, -0.631997 } };

Hi @123uiui
You may need to enable Debug Visualization

scene->setVisualizationParameter(PxVisualizationParameter::eSCALE, 1.0f);

[123uiui]

It didn't work.

[vreutskyy]

Aa, you mean snippet rendering, not debug visualization. Sorry, I don't see what exception you get, but if it worked before your modifications, then perhaps you're doing something wrong.

[123uiui]

I did not modify the original code; I only added a prism convex mesh. This rigid body can be visualized correctly when rendered alone, but an error occurs when it is rendered together with the fluid.

[vreutskyy]

And if you remove the prism, does the fluid render normally?
I could have a look what's happening there if you provide a snippet/sample to reproduce the crash.
