Default How do you achieve this effect?

Im curious as to how you achieve this realistic looking relfection, all i can get is a hot white spot?



Thanks for your help

if you mean the reflection with all the white spots... then you can try HDRI

You might be.

In the main GIJoe pop-up control window, under HDRI Fake, there is a checkbox. That needs to be on in order for your color image to be evaluated/calculated/faked as a HDRI image to achive those cool highlights and reflections that you need

Here is an image for you to see what I mean:

Arrow 1 when this box is checked, you can put your mouse over almost any piece of text in the GIJoe panel, and get help on what it is/does.
Arrow 2 You said you added a color image in this color slot, so I won't talk about that
Arrow 3 when you add a color image to the color slot (see Arrow 2 ), in order for the HDRI effects to happen, this checkbox needs to be checked.



Hope this has helped a little

I did have that checked, and it didnt seem to make any difference. What kind of image should i be using for the HDRI image?

Does anyone have a sample of how this should turn out so i can see?

Thanks for your help so far

Oh, btw, use HDRShop to convert your .hdr images to Floating Point tiffs for use with Maya. (GIJoe specificly)

I believe that targas work too, but I just stick with what Pixho said, and use FP Tiffs
