Mesh with vertex animation material flickering problem

Hello! I’m trying to use the 3Ds Max script for importing vertex animation into UE4. I am following this tutorial and I managed to get the animated material working, however the meshes are flickering pretty hard (I’m attaching a video of the flickering), and I have no idea where the problem is. Could anyone help me with this please? Thank you! Cheers

Disabling dynamic shadows fixed this problem for me, you can try too.

Thank you for the reply, it does look like a shadow issue, but disabling dynamic shadows is not a solution for me, since I heavily use dynamic shadows in my game… I’m more interested in fixing them so they work and look properly on animated meshes.

I believe I have found a fix for this. It’s a bounds issue rather than a dynamic shadows issue.

Open your static mesh that you’ve set your vertex animation on. In the details panel, search for ‘bounds’. Default is 0,0,0 (Min and Max) Set the appropriate values for your mesh. Note: lower values will make your shadows sharper, however, too low and you’ll see your shadow gets cut off. Higher values make the shadows softer.

Hope that helps :slightly_smiling_face:

you can set the bounds using blueprints too, get that mesh and drag line from it and search for set bounds node

This worked for me, although it possibly costs a little bit of performance as frustum culling will overcompensate

Thank you for the tip but unfortunately this doesn’t do anything to solve the problem :frowning:

I have a similar issue, but I solved it by setting detail - material - cast ray traced shadow to false. Hope the answer can help someone else :slight_smile:
