I have attached an image which contains an aerial map and a road. The road has a grass embankment. I’m trying to create grass with similar colouring to the field in the aerial map.

I opened the aerial map in Photoshop. Got the RGB of 3 shades of green in the field. In max I created a composite material with the base material and 2 standard materials. Used the colours from photoshop and smoke maps in the opacity slots.

When I render the colours are very different then photoshop and the texture appears spotty as if I was using a noise map instead of flowing into each other with a smoke map if that makes sense.

Any ideas how I can create a material with similar colouring to the aerial map.

Thanks

Not sure I fully understand what you are after, but why not render an image in Max and composite it in Photoshop afterwards; Photoshop has plenty of tools to do it.
Also the images must have the same resolution.
Tell some more about what you are after; are you trying to match background image with mapped object in Max; that is another story, but there is always a solution.
Be more precise explaining the issue and you will surely get the right tip; here are plenty of guys (girls are fewer, but very knowledgeable) already knowing the right solution.

Thanks for your reply Ivan.

Apologies if I was unclear. Basically I am trying to get the grass in my model to match the grass in the aerial photo. I can’t fix it in photoshop as this is for an animation and not a still.

Why not grab a sample of the grass texture from the Map in Photoshop and adjust it so it doesn’t tile too badly, then use that as the material for the berms?

I’m curious to see your material.  Could you post an image of your material settings here?  And maybe a clearer render, the one you’ve posted is really small and not very clear.

Thanks Ivan and Chris for your responses.

I couldn’t use a sample of the grass texture because the resolution was too low and it looked terrible.

I just got my hands on a higher resolution ortho photoa a couple of hours ago where the grass colouring is similar. So I just made a map out of that using a mix map and mixed it with a noise map.
