How to flush texture cache in Corona?

(1/1)

thetexturedude:
I just started using Corona Renderer for 3ds Max to do some Arch Viz and I am using Substance Painter as my texturing program. Since CoronaBitmap has no native UDIM support, I am using the Bitmap Lookup OSL shader. It renders fine but when I change something in my textures and re-export overwriting the old ones, Corona still takes the old textures and renders it. Have tried it with png and tiff textures.

In Arnold there is a way to flush the texture cache. Is there a similar thing in Corona?

Avi:
Have you tried clicking on reload texture?

Sorry but there is no Reload Texture button on the Bitmap Lookup OSL shader. CoronaBitmap has it but when I load my UDIM textures with as "textureName.<udim>.tif" it doesn't load the udim range and doesn't render properly.  Is there a way to use UDIM textures in CoronaBitmap node?

Avi:
I tried to reproduce this issue but the texture seems to be updating almost in real time without having to reload or flushing any texture cache. Is it possible for you to start a ticket and share your scene so I can try to reproduce the issue and try to find a solution for you?

Thats very strange. Thanks for replying! Are you using the Bitmap Lookup OSL shader and the textures update at render time every time you change them? Or is there a way to use UDIMs in Corona Bitmap node?
