max bitmap loader vs vrayhdri

I’ve been using the vrayhdri map to load hdri skies for years now, but recently someone was asking me how to lower the gamma of a hdri sky when using the max bitmap loader. I just tried it, and clicking override gamma and putting in 0.75 instead of 1.0 did… nothing! Is there a trick to getting it to work, or does it just not work?

thanks!

You should nest it with a 3dmax color correct map and then change the gamma from there. Its an extra step but that could be the workaround

thanks that worked. I’m pretty sure the max CC used to be a bit weird with hdri’s but seems to work these days

im glad it worked, yeah, i used to work with an now outdated plugin but CC seems to work fine

is there any benefit of using the max one vs the vrayhdri loader?

The 3ds Max one is a bit faster for 8-bit and 16-bit textures, as it performs some calculations at reduced precision.
