We have released the first beta of Filter Forge 3.0 for both Mac and PC:
Filter Forge is a versatile 2D procedural texture generation tool that works both as a standalone app and as a Photoshop plugin and lets you generate resolution-independent seamless textures with bump, diffuse and normal maps with resolutions up to 65000x65000 pixels. Here's the homepage: http://www.filterforge.com (http://www.filterforge.com/)
The key feature we introduced in this beta is the ability to use multiple source images (http://www.filterforge.com/download/beta3/multiple-source-images.html) in a single Filter Forge filter. In previous Filter Forge versions, you could only use a single source image or a Photoshop layer, which was one of Filter Forge's biggest limitations. You can load all image formats supported by Filter Forge: BMP, JPEG, TIFF, TGA, PNG, OpenEXR and PFM. Transparency, HDR and floating-point colors are fully supported.
Also, this beta introduces progressive previews (http://www.filterforge.com/download/beta3/progressive-previews.html). One of the most popular complaints about Filter Forge has always been about its rendering speed, and progressive preview addresses this problem. The idea is to give you a rough, low-resolution preview of the rendered image as fast as possible, then gradually refine it in subsequent rendering passes until the image reaches the final level of quality.
The beta is open for anyone – no registration required. Download it here:
