Thanks. Maxon support got back to me and helped solve the problem. I will try "Share Your Idea" and ask if the situation can't be made more transparent.

Yep, between the last version and 24.4, the icon index has changed. Oh, fer the luv of ... Worked great a week ago. Now some of my most used functions aren't even listed. I will have to go back and see what might be done.

SOLVED: OK, Maxon's help was happy to explain.
All the interface icon stuff is still there. It is in a zip file located in the main folder. I think it is Resource.zip? Just unzip the folder, change out the icons and index files, then zip it again. That's it. (probably wise to copy the zip file before tinkering.)

I can't upload a large file here, so you can see my icons and index at:

It's not extensive, I just restored the icons for the functions I most use. Frame selected object, Frame All, Cursor mode, Camera mode, etc, Toggle visible only, whatever.

The underlying problem is beyond understanding. Most of these functions have been around for decades and have always had assigned icons. But their icons have been missing for YEARS. This seems basic to having a user-friendly GUI, and everyone has realized this. The fix seems to be very easy. Does Maxon need someone to make new icons? I will volunteer, and I won't charge any more than I think they are worth.

I worked up a set of interface icons that restore many icons for things I use all the time, such as "Frame Selected," Navigation modes, etc. They were easily dropped into the appropriate folder from v.2022 on, even in 2024. But I just updated it to 2024.3.2, and, YIKES, that entire folder structure is gone! The familiar icons are still in the interface (What few still exist), but the tif file is nowhere to be found. I searched with every variation of terms I could think of, to no avail. Where'd the icon files go?

I figured it out. In one material, the color channel had changed to Color+AO? (I don't know what that is.) FBX export couldn't handle it and choked halfway through. Thanks

I had problems exporting models to FBX a few versions back. Recent versions seemed to have fixed the problem, but I just got 2024.3.2, and the problem has returned! On export, the process hangs and c4d is frozen until it killed and restarted. The exported .fbx file is partially intact, but the materials are missing and/or misaligned, and objects may be oddly rotated.
Is there a setting or plugin that I can use to workaround this old/new problem?
