Hi

I'm just wondering,
I've never used the skydome thing in Lightscape. How does one go about doing that?

After applying the HDRI image onto one, do you assign the entire dome as a WINDOW/OPENING?

if i model this dome in MAX/AUtocad, wont there be a million vertices which would slow down the processing time etc?

Would like to experiment with it, can anyone give advice? or a quick tutorial?

Thanks a million!!

are you shure that LS support HDRI?

hi, i've done that in the past for interior/exterior scenes, to catch both in one shot. make a rough hemisphere over the entire scene (geosphere, octa, 3-4 segments, hemisphere). face the normals inwards and define it as opening. then process it as interior and let it run till 98%-99%. reduce the brightness to 10-20 to compensate for the strong skylight in the exterior part. to get an nice and smooth solution, it also needs a fine mesh resolution for the interior parts and a clean modelling.

I would suggest a different thing:

Place a hemisphere with fine mesh in the scene and a lightsource in the middle of this hemisphere. Then let lightscape do one iteration and stop the process - When you have enabled textures the mesh stores the light and would bounce it back to the scene with the next iteration - now go and merge this skydome to a different scene and let there bounce the light/color information back to scene.

Can some clearify this trick, please.
Wich would be the best way to handle exteriors.
Im starting to use LS on exteriors, and Im very, very far from the interior results:-(

Thanks for the tip

Iam always used it as an opening for the skylight. Could only use it to get nice reflections.....

Gonna test your tip.....

...whats the light source thats placed in the middle of the hemisphere?
You mean like defining one poly on the hemisphere like an opening?

I tried to merge the solution file of the skysphere into another ls file. Crashing everytime

I just saved my scene file as ls file, didnt start any radiosity calculation what so ever, merged my skysphere ls file, where I stopped the radiosity calculation just after one iteration like you said, pushing the run button. Crashing everytime.....

Hmm
Dont know whats going on....
