Hello, I'm trying to convert an object from .dmx to .mdl, but every time I try to compile it I get error and this message appears:

WARNING: DmeMesh[Asylum1]: Non-Unit Length Normal [4957] < 0.000000 0.000000 0.000000 >
WARNING: DmeMesh[Asylum1]: Non-Unit Length Normal Repeated 41 Times

Does anyone know how to fix it?

I'm back here to report a new problem.

I can't export the .DMX model, i get the Traceback error and I couldn't solve it by myself.
I also tried to look for the errors individually, but no success.

I tried to update the .blend, the addon, blender, but nothing seems to work

About the texture:
My bad, I think I misuderstood the tutorial

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=245723825

Both programs are upgraded and I followed the tutorial above to create the qc code. I could send you the DMX file and the QC code so that you could see what is wrong

Ok, I tried it, but the problem with the .qc still remains. Also, when I export, only the DMX file is created, the texture is not saved
EDIT: SMD also doens't work

What do you mean?
Export another file and trying to opening with it?

Which value should i use in "Weight Link Cull Threshold"?
I tried to use everything from 0 to 1 but the problem remains

So, I tried to make a model and export (everything until here was a success). After making the .qc code and trying to export, I got this error:

I tried to look for a solution in this topic:

But still I can't get it exported
