As i have already showed my problem in the fantastic wmo tutorial by @Met, no one had found a solution. Thus, i decided to make a whole new thread about the problem as i have had this problem for a few months now and it is getting on my nerves. It is weird that no one else has this problem which also means that it is something i am doing. So i will list all of my steps and how i import my model into wow.
Now unto the bug. The problem is that for some models, when i implement them ig, some parts of the meshes are transparent but they still have collisions. This means that even while i can't see them, i can't pass through them. However, when i type in "/reload" and i re spawn back into the same location, the textures are fixed. I have tried phantomX's fix which was to delete the ground bellow the wmo but it didn't work.
So first i import the model into 3ds max, than export it from 3ds max as a 3ds file with mapping co-ordinates. After that, i open Mirror machine and using these settings i convert:
I thank put in mpq and go ig and i see the following bug
Than when i reload ig it becomes fixed...
Any help will be appreciated!
