[2.1] exporting Hlms from Blender?

[obelisk]

I'm new to Ogre and making my way through building a test app to see how everything comes together. I perhaps chose unwisely to start learning with 2.1, but it seemed like a good idea at the time

At the moment I'm working on getting a model exported from Blender (2.75) and loaded up with Ogre. I used https://bitbucket.org/iboshkov/blender2ogre to export, and OgreMeshTool to convert to a v2 .mesh, so far so good.

But it appears that blender2ogre exports outdated material files that fail to load:

Code: Select all

Mesh: Loading MrCubeTheFirst.mesh.
Corrupted chunk detected! Stream name: 'MrCubeTheFirst.mesh' Chunk id: 36864
Texture: MrCube.png: Loading 1 faces(PF_R8G8B8,1024x1024x1) with 10 hardware generated mipmaps from Image. Internal format is PF_X8R8G8B8,1024x1024x1.
Exception thrown at 0x76985B68 in OgreTest01.exe: Microsoft C++ exception: Ogre::RenderingAPIException at memory location 0x0056E2BC.
OGRE EXCEPTION(3:RenderingAPIException): Fixed Function pipeline is no longer allowed nor supported. The material MrCubeMat must use shaders in HlmsLowLevel::calculateHashFor at E:\ogre\ogre-2.1\OgreMain\src\OgreHlmsLowLevel.cpp (line 119)
Couldn't apply datablock '[Value 0x0000001c]' to this renderable. Using default one. Check previous log messages to see if there's more information.

I can re-assign a material using code, or replace the generated material with one based on an Hlms and everything works ok.

Is there a newer exporter than blender2ogre? Or plans to update it? Is there something else I should be doing to improve the workflow from Blender to Ogre 2.1?

Thanks!

You would have to ask the blender2ogre maintainer.

Actually yes. There is a WIP project I'm working on called DERGO which can be used to edit materials inside Blender. Because it's very WIP, follow the instructions precisely and see what the videos are doing.

Currently there is no way to export the materials out of DERGO or Blender. However JSON support was added very recently, and if you slightly modify the DERGO server so that it constantly exports the materials to a JSON file in your disk drive, you could get it working quickly (just call mHlmsManager->saveMaterials( HLMS_PBS, "C:\\MyMaterisl.material.json" ) ).

I'm currently working on something else, but as soon as I'm done I'm planning on adding JSON export and packaging DERGO to get something friendlier out of the box for end users (i.e. install with a couple of clicks; automatically launch the server when the Blender plugin is started, choose from Blender where to save the JSON file, etc).

Ok, thanks for the info, I'll check out DERGO and keep an eye on blender2ogre or take a stab at updating it for my purposes at least.
