textures/material transparency

hi all!
i have a question about textures/material transparency, i never get a good result with rfactor 1, even my texture looks nice in photoshop, does not looks the same in game, i never get a solution for this, with tall grass i do not see the texture, i.e. i can not see this texture in game when is not too close to car, and if i put close to car i do not see until last moment. the trees textures looks washed,etc.
the multiple transparency could be a solution but you get the see trought effect.
there is any improvement in rfactor 2 about this subject???
thanks in advance

Seems like you have problem with mipmapping.

First of all check your texture's LOD bias - try using negative values within -2.0 ... -1.0 range.

There could be other reasons (like wrong reference value for alpha test), but unless you provide more details I can't provide better answer.

 

sorry for my lack of knowlodge, but how do i set the lod bias???

 

This is how texture looks in game, i have all graphics settings set to max. Values

 

Save your texture without any MIPs, and test again - looks like K Szcech is right. If it helps, use a lower MIP-count - like perhaps 3 or 4, depending on your initial texture-resolution.

 

You can also set the mip bias in the grass material's texture slot to some value less than 0. -1 usually cures most situations without being too extreme...

 

thank you guys, your tips allow me to fix this, plus i learn something new!!
sorry to start this topic here, next questions on rfactor forum, at least until rfactor 2 come alive
