HDRI problems

[juan.carlos.rioja]

hello folks
How can i get shadows if i'm using HDRI for GI. I think shadows provide by SKY (GI) looks fine in exterior scenes but, HDRI gives nicer results except for the shadows. Is there a way to mix them... :-\

Re: HDRI problems

Check my Audi tt post
I just enable the sketchup shadows. I post a image in the nomeradona's tutorial
where I use also HDRI for background and GI, and I did the same thing.
You can use also additional lights( invisible), to make objects to generate shadows.
Good luck!

Re: HDRI problems

I did that, but I burned the image.Just enable the sketchup sun (Display Shadows button), and adjust the shadows as you like to be.
That's all.

Re: HDRI problems

Juan, I forgot to tell you one more thing, and I'm sorry...beside the sun via scketchup, check the "default lights" in the global switches.Default lights means the sun.
And you can post your render to see what kind of scene do you have.
Also, you can download my "Audi TT" scene, if you like the result, where you can check my settings and where you can find also my hdri map, witch it's a very good map.
I'm not the best "teacher" like other people are here, but I really want to help, when I have the opportunity,so I hope that I helped you too.
Regards,
Stefan

Re: HDRI problems

don't worry stefanq you're a very good teacher ;D thanx for everything.

i tried what you said about the default lights but haven't got anything :-\ when i set a HDRI for my GI light, inmediatly, the options to set the shadows dessapear. so don't know where to modify those.

...

... wait a second... you're trying to tell me that i just have to render my scene whit the sketchup shadows turned on???

Re: HDRI problems

Hi aldz, you can download my "audi tt" scene, where you can find the HDRI file too. You have there all that you need.
Good luck!
P.S. About the blurred look of your hdri, maybe it's a blurred version, witch it's suitable for illumination, so download my scene, get my hdri file witch it's a very good quality one(@ MB)
and put it as "spherical map" as mapping type.
