I’m what you might call, a Blender NEWBIE! Today is the first day that I’ve used it and I’ve run into something which may not be solveable, at least for me it’s not anyway.
I’m using Yafray just to do some basic renders (to get into the workflow etc) and here’s one that I’ve come up with:
It’s lit using Full GI (whatever that means!), no photons. The lighting comes from the sky, and from a Plane mesh like a light card. My problem is with the shader for the light card, it seems that all of Blender’s values have locked ranges when it comes to colours. That means that my light card can only have a very limited light strength.
I know I could probably just use an Area light, but coming from Maya where you can have huge crazy values (in the negative also) for most attributes, I’m used to using light cards (or just any object) of whatever brightness I want. You can do that it XSI and Max too (in Max you use an Output Shader to remove the value limits).
Anyway, to get the light card as bright as it is, I turned off ‘Clamp RGB’ and used a Blend texture set to white, with the Brightness set to 2 (the max). It’s mapped to the Color, Emit and Ambient attributes. It’s the best I could come up with, with my whopping 2 hours of experience in Blender. My next idea is to just create a pure white HDR image in HDRShop (or whatever) and apply that to the card instead. I assume that would work anyway.
My question is, is there a better way around this value limiting? Can you turn it off? Or can I map the colour with an expression or something instead?
