2 texture blends, 2 UV sets.. whats the penalty?

Blitz3D Forums/Blitz3D Programming/2 texture blends, 2 UV sets.. whats the penalty?

Hey everyone!

I am thinking of creating every object in my world with 2 UV sets and 2 different textures.. I want to do this because then I can add,, say moss to a tree, while not needing to mess up the wood texture.. I can add seamlessness to a tile-looking texture by adding random spots of overlay..

Example.. if I have a room made up of a tiled brick texture..
boooring ^^ but then I add a Masked image of several tileable cement splats which I put here and there.. voila, not so boring ^^

The thing is... will this severly affect performance? Im talking EVERY object here..

This is the method Im gonna use:
cube=LoadMesh("test.b3d") 
PositionEntity cube,0,0,15 

; Load texture 
tex1=LoadTexture( "brucks.png" )
TextureCoords tex1,0
tex2=LoadTexture( "rainbow.png",4)
TextureCoords tex2,1

TextureBlend tex2,1

; Texture cube with texture 
EntityTexture cube,tex1,0,0
EntityTexture cube,tex2,0,1


No alpha... just mask..
