Having some issues working with 16 and 32bit images generated by displacement painting applications and LW. LW seems to work fine with grayscale maps but if the image has RGB colorspace, the image comes up solid black and doesnt render :( I'd like to at least work with 16bit normal maps).

Can someone else confirm this?

As a temporary fix, the following worked well:

32bit Floating .TIFF can be converted to HDR easily with HDRShop.
This seems like overkill but LW will treat the image the same for displacement as it would *if* it could read 32bit float .TIFFs.

16bit RGB converted to 16bit Gray inside of Photoshop CS2. I set up a batch droplet to expedite the process of converting since it looks like I'll need to do this frequently.

I'm sure there are others.

LW needs to support 16bit RGB .TIFFs and 32bit floating .TIFFs in order to support the next generation geometry sculpting application(s).

ditto, this will be needed very soon.

I take it you all have seen the ZB Nodal displacements, and Normal Maps?
video, using subtract and multiply nodes with 16bit TIFF's right?

And you are all also aware of Lynx's third party 16Bit TIFF Loader for PC?
for LW8.x right?

:)

yes, but we're especially talking about the 32 bit kind generated by another program...

I'd certainly find GeoTIFF support handy...

And neither Lynx's, nor LW9 support RGB 16bit tiffs. It does support 16bit Grayscale TIFFs, however.
