Material with no self shading

[sassom]

I'd like to make a render of a scene, which has a photoscanned environment. This environment obviously has shadows baked into it's texture already, because the texture was built from the photos which the model was generated by.
Is there a way to make this environment-object not to receive self-shading, but only to receive shadows or GI from other objects?
Because my problem is if I use simple VrayMaterial with it, the parts which are in shadow, become too dark. So I'd like it to be partly a matte object, which shows it's diffuse color by default, and receives cast shadows and GI only from other objects.
Any suggestions?

Thank you,
Gábor

If it's a still, you can do a first render with shadow disabled and than making a quick second render and giving a matte material to cach only the shadows.
When I use billboards I do in this way, but there must be a method to prevent directly self shadowing (forest pack allows it)

Turning off Cast Shadow option from the Object Properties should remove the self-shadows from the object and it will still capture the shadows and GI from other objects.
If that's is not what you are looking for would you please provide an example scene along sample image with the final effect you are looking for?

Thank you for both for the suggestions. I tried both methods, I turned off the casting shadows option, this helped. Also, using render elements was my final solution, where I applied diffuse filter to the photoscanned object in post production. Blending it with some opacity, I could get the image closer to realistic look. But eventually, it's hard to produce photorealistic image with photoscanned objects, because the scene could have duplicated shadows. One from the scene, and others from the texture itself.

So better solution would be to somehow retouch the texture itself.

Thank you anyways!

Glad that this tip helps a little bit, of course we might find other ideas if we have the scene in front of us.
