Realism without HDRI

TTYO · 08-05-2007, 06:42 AM

I just don't understand, even with the isolated light source pass it still doesn't look as good as HDRI.

Scene without FG

GI pass

Isolated Light source pass

Final composite

The only other way I would even think that would looks somewhat as good as a HDRI is by having a scene with fully textured objects surrounding it and making sure the lighting and rendering is as close to realism as possible. Hopefully the light bounces/shading would make the object you’re focused on come alive, but yes it's just simpler with a HDRI.

Your scene looks flooded and awash with light. Consider getting rid of GI or FG to reduce the amount of light in the scene. I bet a little color would also give it an edge! Splash a multi-sub object material on those walls and make that image zesty! Remember: realism is a combination of modeling, lighting, rendering, and materials!

Here's something new.....

Yeah thats pretty good.

I use HDR, and find it limits me, since I use Vray, and just place one in the map channel. I find though that an object I'm rendering only looks good from one spot, so since its in a map, I have to rotate the object, not the camera.

It can get annoying sometimes.

The only way around it is to model an entire scene like Sip said, for instance a room to render in, etc, even if it was set to invisible by camera.

l I can see in my images for example this one, the HDRI version looks more "real" than the cg one.... cause I work with Cg scenes all the time, I want to know how can I make cg-made scenes more "real", cause I only rely on HDRI for outdoor lighting than interior lighting.

I think it's the isolation of the light object but make the scene unlit by the cg-light......

A few lighted planes will give the illusion of windows, and coloured walls on that box will bounce more light around, creating a depth effect that matches what real rooms would do.
I also tend to place boxes and spheres with different colours around it, and then hide it from camera. This would simulate objects in a room.

Still, its nice for studio renders.

Here is another try at realism.
