I need to import thousands of hdr files. They are imported with the wrong size and mipmap settings, I tried to use the property matrix to edit the textures but it crashes ue4 everytime. Small batches of 5 to 10 work in the property matrix without crashing, but this would take far too long.
Is there another way to edit the texture settings, maybe a way to set the default so ue4 just imports with the correct settings?
Having same issue, any solution?
You can use rdTexTools (on the marketplace) - just select them all, right-click and the options to resize and set LOD are in the context menu…
The crash might be caused by the Property Matrix simultaneously loading a large number of textures for editing.
If you’re still experiencing similar issues, you can try my plugin, AssetProcessor. It’s a versatile bulk-editing tool for asset UProperties, including those only modifiable via C++. The plugin modifies matching assets sequentially instead of loading all textures at the same time.
Below are the YouTube video link and FAB link—hope this helps!
