I had similar errors. I've been fixing some of them over time and added function to convert .tx files. I've attached modified script.

You have to edit script and change those lines at the start:

-- config
img2tiledexr_path = "G:\GFX\TOOLS\img2tiledexr.exe"
maketx_path = "G:\GFX\TOOLS\maketx.exe"
defaulttx_parameters = " -v -u --oiio --checknan --filter lanczos3"
-- config here

Just put correct paths to converters. If you don't want to convert and just change bitmaps to VRayHDRI loaders, you don't need to edit those.

Best,

thank you Tomas!!
is it better to convert it to tiled exr?

[wyszolmirski]

I added tx support to test this out. And I didn't see much difference from tiled exr other than smaller filesizes (if you don't need 32 or 16 bit).

But that's something worth checking out more.

I want to add also support for converting files from inside VRayHDRI. As we always use it for loading textures... and at later stages we tend to convert it to tiled if we hit memory issues.

In general what I've found is this:
jpg/tga loaded via Bitmap is slower than loaded with VRayHDRI
Usually tiled exr / tx render a bit slower than jpg/tga but it can save huge amount of memory.

Nope. As you know, we are not very good with release dates But I can get you a preview build if you are interested.
