inf numbers in vraysamplerinfotex

[sukistar]

hi,

I am getting infinite numbers (that turn to nans in nuke) when using vraysamplerinfotex on large scale scenes.
they usually appear around values of 65.000. is this a limitation of the vraysamplerinfotex or due to half-float-exrs?

thanks

What are the values in the V-Ray frame buffer (when you right-click the pixels)?

You can force 32-bit EXR output with the following MaxScript:

renderers.current.output_rawExrUseHalf=false

Best regards,

the values in the framebuffer are way over the 16-bit limit.
using full-float indeed got rid of the NANs. they turn to INFs when the nuke viewer is set to half-float (otherwise they show correct values) so obviously that was the problem.

this is not an issue when using the vray framebuffer. unfortunately I just gotten used to the comfort of writing scanline-exrs from max vfb.
but even though the exr-writer offers an option to safe as full-float, the max vfb does not appear to produce it.
