[fixed]mipmap problem

[Randajad]

Hello!
I uses 24 bit textures and make transparent key on 255, 0, 255 color.

Code: Select all

 
    static const SColor transp_col(0xFF, 0xFF, 0x00, 0xFF);
    g->driver->makeColorKeyTexture(tex, transp_col, true);
 

When i viewing my "tree" at far, then it's display me that color like:


But when i make my camera near everything is ok:


Also i tested and found, that there is NO problem with opengl device.

Mipmaps, the smaller versions aren't 255, 0, 255, they are some blend with green and that.

Use proper alpha channels.

[Randajad]

Sorry, but i can't. Then why opengl works ok?

[hendu]

Sorry, I was wrong. Colorkey textures are proper alpha textures inside irr.

This is a dx device bug then. Maybe it's mipmaps not properly updating.

[Randajad]

My fix:
cnulldevice.cpp:1070, add:

Code: Select all

 
    texture->regenerateMipMapLevels();
 

I think it is right way to fix it.

Moving this to bugreports

Yeah, there's one after createNormalMapTexture too, so seems correct.

Ok, fixed as suggested. I think these methods will sooner or later be moved to image converter methods, which only work on the basic CImage. This is far more efficient than doing this conversion on the textures. But that has to wait some more.
