hdri lighting
show user profile  debodeebs
i have my interior set up with just an hdri map, the scene is lit ok but on one side of the room its badly burnt, ive tried controlling the exposure in photoshop but that just affects the whole lighting when all i want to do is just control the burn amount and leaving the rest of the scene just as it is.

any ideas on this please.

cheers

ash

Haven't checked all the links but would be a good watch.

Check the output settings (within the material editor), you can control the RGB and overall curves.

thanks mike but both sites you and herf has suggested is just setting up the lights which i already know, i just want to know how to control the brightness in just parts of the scene.

Try a different HDRI, or rotate the one you have, there's a horizontal rotation option in the VRay HDRI params, maybe you could rotate the burn to another part of the scene....a less obvious place.?

If you change the 'white point' amount in the load settings that open when you open an HDRI, you can get rid of the burn.

Make your own HDRI? Light Studio seems to be developing into a pretty comprehensive tool.
