i have a file that when i open it the bitmap previews does not show a preview unless i navigate to the bitmap once more and select it, is this some issue with the vray materials? will send a scene to support ![Capture.JPG](https://europe1.discourse-cdn.com/chaosprd/original/3X/a/e/ae252a7b56e0225dac92af042126840a3d4ab7e0.jpeg) ---

Probably an asset resolving issue. Check the asset tracking dialog when you open the file and check where the bitmap is pointing. ---

Does the same happen if you open the file on a different computer? If yes, maybe we should take a look at it. Best regards, Vlado ---

I had this issue a million times already, I don’t think it’s Vray related. The only thing that helps is delete the bitmap node and create a new one. ---

The only thing that helps is delete the bitmap node and create a new one. yeah your right, its the only thing that works but its awful when its a big scene, the origin of the file is suspect to me though, i think issues were there when the file was originally created, i didn’t start it so i guess that’s where it is and am not sure what version etc was used but when i create my scenes from scratch all is ok, clean and perfect ---

It renders just as fast it seems. ahh, good you took the time to test it, for me now it seems the issue is with using large res images with the hdri loader, i posted a video below, it can’t display the images as is in the viewport, so i guess then other than using it for loading hdr.exr. etc images there is no real benefit to using it over the regular bitmap loader for regular bitmaps? ---
