When I tried to import a certain normal map in UE5, it fails to import and crashes every time. When it comes to other normal maps it’s no problem.
The file size of the map is 768mb.
So I thought this is because the size is too big, but when I imported albedo file with the same size, no problem.
Does anyone has the same experience and know how to fix it?
The crash report say the following;
Assertion failed: toPtr == toEnd [File:v:\devel\projects\oodle2\texture\blocksurface.cpp] [Line: 549]

Take into account that normal maps require internal conversion, which might be the area where the file size is the problem.
Albedo stays in it’s state from import to uasset conversion, normal maps do not.
Try making a copy of the normal map reducing the size and doing test imports and see where it’s limit is
Thanks for the comment.
Just tried to reduce the size(ultimately 16MB) and imported again but it crashes.
So now I’m guessing the issue isn’t the file size.
By the way, when I imported the map in other software Houdini, crash didn’t happened.
The error would indicate that it has something to do with oodle2 compression (new format in unreal 5) maybe try changing the compression method to another?
Thanks. Is it(changing compression method) “Shader Compression Format” in Project Settings?
Just go to Plugin and uncheck Oodle Network and Oodle Texture as the image attached. And finally successfully imported the normal map.
Thank you so much!
Glad to hear you will be able to continue your project without this problem. Best of luck with further progress.
