Interior MipMaps?
by Eric Forhan · in Torque Game Engine · 08/02/2003 (8:03 pm) · 6 replies
I'm having some problems with interior textures going from a nice high-res texture straight to a very blurry low-res one sooner than it should. It doesn't happen on all interiors, only some. Does anyone know if there is a way to adjust this?
I use QuArK 6.3.x w/the latest map2dif. Radeon 9500(w/128MB).

I believe it has something to do with the scale of the textures. What are their scales? And what are their resolutions?

I had these problems too... I don't seem to have them any more.I believe it has something to do with the scale of the textures. What are their scales? And what are their resolutions?

it seems every texture actually has 2 opengl textures, one normal sized, and one 'small' texture which is a low res texture
i'm not entirely sure, but maybe what you're seeing are the small textures being applied after a certain distance..

Mipping simply takes the avarage color of 4 adjecent pixel and make a new one.
So the higher texture resolution the better it "mips" so to speak.

The smaller the texure the faster will it blur as there is not enough "pixel infomation" on the texture to work with.Mipping simply takes the avarage color of 4 adjecent pixel and make a new one.

I no longer have this problem, but I remember it being a pain in the ass.

Yeah... but sometimes it mips 512*512 textures faster then 12*128 for example. The mipmapping is a bit buggy. On the same distace it sometimes blurs certain faces and other not, altough they use the same texture. I no longer have this problem, but I remember it being a pain in the ass.

Scaling the texture above 1x1 (or close to it) seems to be the cause of this.
