  1. Changing the Color Space RGB of the Normal Map from Default to Linear fixed the issue in the corrupt scene. But what is strange is that in the other scene, it's set on Default and works. Weird.

     

    After investigating a little further, I noticed that the color spaces for each scene are totally different. I've never messed with the Color Space settings before.

    Well, glad it looks as solved.

  2. I meant the file format (.hdr), not HDR as in High Dynamic Range. Probably I shouldn't use the caps.

    For now if I want to load it into 3D-Coat, I need to manually convert it to .exr first.

    Most of HDR environment maps on the Internet usually come as .hdr files, and majority of software supports this format. Hence my question.

    It's not a big deal, just something that would be nice to have.

     

    The Radiance format (.hdr) is actually just a standard 24-bit image, with an additional 8 bits worth of brightness data per pixel. So you have the standard RGB between 0 and 255, and then an additional channel going between 0 and 255. All the RGB channels are then multiplied by the forth channel, so each pixel is somewhere between 0 and 65,025. This means that the brightest pixel in an image will be no more than 65,025 times brighter than the darkest non-black pixel. However, the big problem with Radiance is that a single pixel has the same amount of color fidelity as in a regular 24-bit image (like a JPEG or PNG). If you have a pixel where the red component is 65,025 (255 times 255), the green and blue components can be either zero or 255 (or higher), nothing inbetween. With OpenEXR, this is not the case.

    Also, a 32-bit floating point image has four billion brightness levels. With all three color channels, that makes for a grand total of almost 80,000,000,000,000,000,000,000,000,000 different colors. (That's an eight followed by 28 zeroes.)

  3. It would be nice if Blender didn't recalc the normals when edit mode is activated. Blender doesnt support custom/edited vertex nomals AT ALL at the moment and constantly recalculates all vertex and face normals using its own algorithm, so: the normals are imported and then Blender just overwrites them with its own calculations.

    Could be the LWO import-export project a solution ? i duno. May be i will try it later.

  4. Yes i was reading your post

     

    there is 2 reply

    Do you tested this solutions in your project ?

    Will be nice to know the result after it

     

    Are you using color-space conversion?

    Did you disabled color-space conversion on normal map image file?
    It looks too bright to me = it has been passed through color-space converting routine..

     

    Yes, I'm wondering if you just need to make sure it's set to Linear in the image properties, could it be that simple?

     
  5. I remember some troubles when you edit any object inside Blender -the normals are automatically recalculated-

     

    Duno how to help with this task

     

    you tried asking at Blender forum ?

  6. This issue is related to Win7 technology: Cpu core parking

     

    What is core parking and should you adjust it?

     

    If you are an owner of a new multicore Intel CPU for example Intel core I7 and Windows 7 or Windows Server 2008 OS, you already might notice that some of the cores in your resource monitor are marked as parked. This is a new feature of windows 7/2008 operating system that is made to balance energy consumption by your CPU.

     

    I tested this app to unpark my CPU, but backed to an old registry state because i dont feel ok the multitasking performance with the changes

    >>> *= USE this app at your OWN RISK =* <<<

    Warning: your are modifying the registry. Take care.
