Beta 4 of Inspire Render and Inspire Studio are available

In this beta we focused primarily on shortening the list of bugs we have in queue.

Some notable improvements are the revised camera panel (easy/expert mode), RealTime GI improved and blurry reflections added, .fbx/.gltf/.blend importer.
We also added ALT+Click in the texture widget to bring up the texture tone editor and SHIFT+Click to remove the texture.

To download the package go the landing page:

Here is the updated license file. This time we made it up to August 30th.

      • The menu button is now slightly bigger. [JQL]
      • Shortcuts: SHIFT+Click on texture to remove the texture, ALT+Click to open texture edit panel. [JQL]
    • Can now save into .iRenderPack to include all textures in one single file.
    • Real-Time rendering improvements and fixes. This includes:
      • Scene luminosity is wrong in "Global Illumination / Simple" [Rombout]
      • Better Global Illumination calculation
      • Objects interreflections ("Blurry reflections")
      • "Use Surface Color for Bump" is not working - fixed
      • "Use Surface Color for Bump" does not take into account texture edits - fixed

    • More speed-ups when loading complex scenes

.blend importer is a great move! :thumbup:

Still no animation in this version ? It's difficult to find time to test this new software so I'll wait untill anim is added to dive in.
