Udim rendering black

[marchermitte]

Hello
I'm using the 4.04 lightwave plugin.
Loaded the udim in Lightwave image editor, connected a glossy mat , Image texture set to tiled image, picked the udim image in the list, there are 8 tiles in the u direction so i entered 8 as the max tiles in u and 1 in v (tried also with the numbers of the tiles, 1001 to 1008) and IPR renders a black globe instead of the earth texture I'm expecting.
Any trick?

Thank you

Must be the texture size, might be too big even with out of core enabled. The texture is made of 8 tiles of 1334 mb each.

How come the out of core doesn't take care of the texture memory hit?

Hi,

What is your out of core configuration? Perhaps you have not reserved enough CPU RAM to allocate space for these large textures. Try again using at least 16 GB of RAM usage limit or more.

Thanks,

I allocated 20 gig of Ram to the out of core option.
My video boards are 2x gtx 1080 ti with 11 Go.
Just checked Lightwave while rendering the scene (natively) the task manager shows 4.5 Go of ram for the layout.

Hmm, I'm not sure what could be the problem in any case. So if you reduce the textures' resolution (or you load less textures), all works fine? What is the resolution of these textures?

Thanks,
