Hello guys, I was trying to implement new terrain shader in my Milagres Kart track but something is not working as it should. I set up all four textures - Clean grass (Channel 1) - Rough grass (Channel 2) - Dirt (Channel 3) - Pattern to multiple with all 3 (+ alpha with second pattern) (Channel 4) The three first with Specular map in Alpha as described in Track PDF. After that I created the normal maps with alpha maps too use as "blend pattern" as described too. I set up everything in max and start the blend with vertex color as described in PDF too... After seeing the result in game something strange happened... The first two textures (Clean grass + rought grass) blend perfectly but the third map (dirt) becomes blurry... all mapping was done correctly in 3ds Max for the 4 channels. I did a test changing rought grass to stage 3 and it becomes blurry too. When I put dirt in stage 2 it becomes perfect... Any idea? I'm not in home now so I can't show you a screen shot but later I will post one. Thank you Edit: Screenshots from problem
Are you using the UVW Map/XForm/Unwrap modifiers to map the channels (good), or are you using the Tiling and Offset parameters in the gTex panel (bad)?
I tried two ways and then when I was saving a print of my settings in mx i found the problem.... Facepalm... Bias was positive.... I usually use bias -2 but i must have clicked wrong yesterday in a hurry and didn't realise that this was bad... now with -2 all went fine Thank you very much Luc
Good to see you got it to work . Have fun experimenting with the shader -- it does take a bit of time to develop some ... Fingerspitzengefühl. By the way, negative MIP Map bias is blasphemy on this forum .
It's a leftover from the old days when people couldn't afford to run 16x Aniso, and is now the biggest cause of aliasing when you do run Aniso. Recent ISI tracks use MIP Map bias 0.0 for nearly all materials; exceptionally -0.5 or -1.0.
Sorry for the delay Raul. “Multi layer grass / dirt” You have the shader description in pdf that ISI provided http://imagespaceinc.com/downloads/rf2/modsresources/rF2_Terrain_Shader.pdf
