Hello,
I noticed a typo in the surfaceparms article in the SD Wiki, about “roofssteps” instead of “roofsteps”. It looks unnoticeable, but when I tried it in my shaders I didn’t know why the texture was keeping the default sound… The beginners will not find it by themselves maybe 
I ask it here because I can’t find the Register part, only Log In.
Thanks 
there are more typos with the surfaceparms, imo it are the spaces between the steps that do not belong there. But when I last reported it 2 years back there was no reaction^^
I should use the Search tool before posting xD
Well I took example on the core shaders, I can script the type of the texture at least now… First thing to do as a beginner to learn quick 
The |>Bunker<| Wiki is also nice, it has some brushs generators and good tuts links:

Going a bit offtopic again…
