Agricultural landscape

PLSM is a wonderfull addon , bravo tuan !!
I am using PLSM to visualise agricultural landscape. A model simulate agricultural policy and compute a land cover map. From this indexed map I generate a big resolution texture to drap on the terrain that is splitted in many 1024² textures drapped on each page of the heightfield (is that clear ? sorry for my bad frenchy english )
You can see screenshots there :



I would like to drap another texture layer to visualise indicator (e.g. add a red texture over the textured terrain where alpha indicate the percentage of nitrate on each field). How can i do ? Projective Decals? or anly modfying the ImagePaging material ?

And a second question, can I use Splatting instead of drapping image ? I know that the number of splatted texture for the rendering is limited ..but perhaps there is a solution to override the prob?!

Thx for any answer

Nice project.

Splatting is also the answer for the "red" nitrate overlay alpha. (can be done very simply in a shader, but also with a red texture)

Splatting is the answer provided you do not have infinite layers but a reasonnable count.

Using shaders you can go at least 4 layers per pass, and you can have any number of pass you want, each pass slowing a bit more the application.

4 pass is rather common and give 16 you 'layers'.

using shaders and some tricks you sure can go above the 4 layers per pass, but go there only if you need to.
