Hello,

I have problem with Unreal Engine Editor.
When i try to import an FBX with materials and textures (Environments or Characters) editor crash.

If i toggle off “import Materials” import go fine with some errors

This not happend with all FBX but with fbx imported fine i have visualization problem.
I see wrong texture applied on model(example: Black area on th texture, strange deformed texture.)

I have already import this models on other engines and they work fine.
is possible have help?

There is a guide to import correct model?
Thanks.

If you are using Any Autodesk software,be sure to use 2013 FBX when exporting.

Yes i use 3dsmax and Maya to work on model.
I try to export them in 2013/2012 FBX Format but editor crash again

Hi,

Thanks for your report. Could you attach a sample test asset that causes this crash that you wouldn’t mind sharing?

Best,

i resolve one of problem i think

i see guide to import an FBX and i notice my model not have material named with skin## method

I have renamed material with _skin## and now import with material work (Characters)

But model come without texture place on that, and in viewer every material is set to “None”

for Environments problem remain i need to import big scene and if crash with large model is not good for me.

there is a size limit for model?

Thanks

I’ve entered a report for crashes you’re experiencing. It sounds like there are errors in files you’re importing, but it shouldn’t be crashing editor. I’m glad you were able to find a workaround for one of them!

I suspect problems you are having involve way you’re exporting your FBX files. Your second FBX file (Re2First.FBX) is not too large for editor, so problem probably lies somewhere else in FBX.

Have you gone through import documentation on Unreal Engine site?

I’ve fixed both your issues in code and it should be fixed in next update. You can work around these for now doing following:

  1. For your character mesh you have materials and textures that are named same thing. You cannot import a material and texture with same name to same location. Now it will create a unique name for any textures found to be same name as material. You can fix this on your end by renaming your textures to not have same name as material or each other.

  2. There is no size limit for your model but you can only have 64 materials per mesh. This is to avoid a huge number of draw calls. I would suggest you break this model up into smaller pieces if you require that many materials.
