Texture ID problem. Need Help !!!

[harikumar001]

Hey Guys,

Have a good day.

Stuck with a problem yet again. Been working on an application for a few months using TV3D. My users can load models into the application and change their textures. Everything was working fine, until I recently discovered that whenever I have two or more different meshes using same texture file and I delete a texture in my application using textureFactory.DeleteTexture(ID_of_any_one_mesh_sharing_texture), and add a new texture to that slot, the textures on all other meshes get updated.

Here are some observations:

1. I took output from the debug file after dumping textures
Slot 1:C:\PIC1.JPG   TEX1
Slot 2:C:\PIC2.JPG   TEX2
Slot 3:C:\PIC1.JPG   TEX3
Slot 4:C:\PIC1.JPG   TEX4

This is before I delete anything. When I execute Globals.GetTex("TEX1"), Globals.GetTex("TEX3"), Globals.GetTex("TEX4") all these return the same TexID. From what I understand, TV3D keeps referring to the same slot where the texture to be shared loads for the first time. For instance, here PIC1 is loaded in slot 1 for first time and everytime a texture using file PIC1 it asked to return an ID, it returns the same value 1.

2. The problem is solved by using textureFactory.SetTextureSharing(false). But I do not think that would be resource friendly.

Is there a work around to this problem?? Please help guys.

Well your texture files should have different names however, you if you know their are going to be different files loading in with the same name you can call  textureFactory.SetTextureSharing(false) and then back to true again once you finish loading those.

Otherwise really you need to make sure the names are different in my opinion.

Thank you Toaster

I am not loading different files with same name, I am loading same file with different names which is giving me the problem.

Same here, what I did to fix it was ask for the id after creating it, not trusting the return value of the create func.

I handle them myself but have to keep sharing true or models with textures cause a major upset when trying to delete textures.

OH and I keep a list as the same id is issued to any texture that matches an already loaded texture, this way I decrement the list for that id number and actually delete it when it hits 0.

i.e.   IDarray[] can be fixed or growing

IDarray[gettextureid()]++  to add to list
IDarray[...]-- to delete
if IDarray[...] < 1 ( deletetexture(IDarray[...]) )

unfortunately textures loaded with models will sometimes use an already loaded texture so I name all my textures with a prefix to make them unique from my model textures.

OH Yea, TV assigns the id based on the filename (complete) not the name you give it.

Thanks you TecnoBacon, that was really helpful 

I guess managing textures myself is the only way out.
