Hi! Is there a chance of having ECW-support ( http://geospatial.intergraph.com/products/other/ecw/ECWPlugins/Downloads.aspx ) implemented into vray? There is already a 3rd-party plugin doing this: http://www.terratorrent.com/index.php?route=product/product&path=65\_123&product\_id=6904 would be a k…

Hmm - Tiled EXR files might do this for you?

There used to be a plugin called WavGen that could read ECW files and it worked fine with V-Ray from what I remember. Other than that, like joconnell suggested, tiled OpenEXR files might an alternative approach. Best regards, Vlado

Hi Guys! Thanks for your answers! The link I have posted was the WavGen-plugin, which is quite expensive (500 €). We’ve already tried tiled EXR’s. Converting a 80k-texture to a tiled EXR doesn’t work if you don’t have a LOT of RAM (even a machine with 64GB RAM fails).

We use wavgen. Although expensive it is unavoidable when you are constantly dealing with massive ECW files from clients. Just another cost of doing business. We worked out a deal with the guys who make it. Maybe contact them and see if you can work something out. I have tested tiled EXRs previo…

Well, the other option is to try maketx to make it into a .tx file; it might more memory-efficient (but then again, maybe not). Best regards, Vlado

I wrote an email to the wavgen-guys, still waiting for a response. We’ve als tried .tx-conversion without success. Vlado, what are the chances of getting ECW implemented into vray?

We’ve been using maketx by OpenImageIO 1.0.5. The conversion worked, but we are having issues with RAM-usage during rendering. (My partner already contacted you regarding this problem via email.) You can generate ECW-files with GlobalMapper for example. Best regards Tobi

Ok then, I will check with the support guys; btw which V-Ray version are you using? Older builds had issues with tiled exr files in VRayHDRI. (Note that you need to use VRayHDRI, not the 3ds Max Bitmap texture). Best regards, Vlado

Which program did you use for it?

Vlado, what are the chances of getting ECW implemented into vray?I don’t know yet; plenty of other stuff to do first How can I generate these files by the way?

Best regards,
Vlado
