iray Tip: Get rid of render image clipping and add EXR output to iray

Jimbow

If anyone's familiar with Mental Ray and the Mia Exposure shaders, it looks like if you go to tonemapping in the Render Settings under iray in Daz Studio you can change the Min and Max values for the Burn Highlights and Crush Blacks settings, using the parameter settings (the small cogs to the right of the sliders - just right click on them) to higher and lower than the seemingly current limits of 1 and 0 (which, in practice, currently clips the tonal range). This emulates Mia Exposure's maximum overexposure and underexposure settings.

Combined with adding a beauty canvas under the Advanced tab, which adds an exr render to your folder as well as the 8bit render, this makes iray in Studio much more powerful and useful for grading in your compositing/image processing software of choice (Photoshop, Fusion, etc)

For anyone unfamiliar with Mia Exposure in Mental Ray and can't figure out why my weekend just got better: https://www.google.co.uk/#q=mia+exposure

Thanks to DAZ_cjones for the exr output pathway in Studio.
