Greetings! I used the same model from Vue4Pro, and also the St Peters HDR image. I think yours (Veritas777) is a little better because you have de-emphasized the green shades more than I was able to. Note how red my HDR image is, compared to Veritas' image. His is more neutral. Also, I didn't end up rotating the scene to the same place. However, I don't think this is not too bad since there are slightly more shadows here, maybe giving some more depth perception. But that's more personal preferences, I think. BTW, my render time for this 800x600 image (Final) was 25 minutes! So 1024x768 would probably be 35-40 minutes. Also this version is somewhat compressed for the web. I guess close, I just wish I could get more green out. I think my approach is wrong. Thanks, Norm

Here's how to get the green out. Change the color of the Overall Skylight Color.

I would also recommend trying some of the other free HDR files. Each offers some unique lighting characteristics. The St. Peters HDR was just my own starting point- as I've tried others I'm amazed at how wide-ranged HDRI lighting can be. It just gets EVEN BETTER...

Thanks for your reply. Well, I had printed out your earlier posts from the first ones you posted with HDR images. I have that swatch as close to that shade as I can see comparing them on my monitor. Still too green. Also, my Sky Dome lighting gain is pumped way up to 13.20, to get it up to this level. I don't see anything else in this capture that is different from mine. Hmmmm. Gotta think some more. My hdri image should be more neutral, like yours is; closure to white. And yes, I'll certainly try some of the other hdr images; right now I am just getting my feet wet, so I wanted to try to duplicate that first image. For me, I was just not expecting a Vue image to look so good, so it took my breath away. The others that followed in your posts only confirmed that. But I am using that first one as a test. Norm

here's the link to a FREE light probe gallery where you can download more HDR's. I would suggest you try some OTHERS on your model- and you could see a LOT of difference.

Try maybe "Campus at Sunset" or "Funston Beach at Sunset" and you will see that your Gain settings and Color settings need to be changed. I do NOT mean to imply that the EXACT settings you see in my screen-shot are EXACTLY what your settings should be. The screen-shot is just to show WHERE the key HDRI controls are- your GAIN and COLOR may very likely need to be changed to other values.

EXPERIMENT- try different settings and SEE WHAT HAPPENS!
Once you see what makes it REDDER or BLUER- you can then fine tune it even more.

It's like taking pictures with a new camera- you may likely take some BAD pictures before you understand how to take a good picture with your new camera. It just comes down to experimenting--- after which comes experience!

Hi veritas, following your instruccions to get a good result using HDRI lightning i got the next image.

Wow! This is better than mine! Very very good lighting. Norm

Great- all you have to do to increase the light on the Trice is to RAISE the GAIN. Of course- this will start to wash-out the tops of the buildings in the background... --However, if you change your scene rotation (select Camera and Model) you can slowly rotate it until you find a BETTER lighting angle- if there is one. Obviously- that particular HDR is a very late afternoon scene- so that is the kind of lighting you have to work with. So, this is what makes HDR files interesting, and why each one is unique- you have to figure out if a particular HDR matches what you want to achieve. Look for HDR's with a wide sunny sky- if you want sunny sky lighting...

Very true veritas, I had to rotate the scene to get as much light as the image gives. I did raise the GAIN, before it the image was more dark. Every HDR image gives you diferent kind of lightning, so you have to try until you feel it is the correct one for your scene.
