Hi,

I'm using Blender2Ogre to export ogre mesh. It seems like the exporter uses morph animation instead of pose animation (morph animation is similar to pose animation as described by ogre http://www.ogre3d.org/docs/manual/manual_78.html).

It prompts error when attempt to convert mesh.xml to bones

        Exception in thread "main" java.lang.IllegalArgumentException: jointIndex: -1

I backtracked the code and notice jme library in Bones does not support morph animation. Do we have a newer jme library which support for that? If we use latest version, does it break anything?

Hi Egon,

I would like to make a depth of field effect by using post proccessing. It requires rendering the object z buffer in 1st render pass, then combine with main scene with a custom dof shader set to the framebuffer for post processing. To render the z buffer, we need to render the scene on a texture match with the screen width and height. I'm thinking of using NPOTTexture, but you mentioned in doc saying NPOTTexture is preferred to be in power of 2 as it's not supported in some devices. How should we do in this case? I worry if we create a power of 2 NPOTTexture and it does not match to screen width and height, we might have some texture size ratio problem. Please advise, thanks.

Hi egon,

Is it possible if you could add delete feature for texture that is virtualized to memory card? Or add delete when textureManager.unload() is called.

Reasons to have this:
1. In live wallpaper, there are occasions where only required textures are loaded, based on user settings in preference.  To avoid loading all textures during app startup (which can be slow),  only one required texture is loaded.
2. Virtualizer.cleanUp() can't be used as it will clean all other textures which are still in use. It also cleans up the shared texture from other Wallpaper instance too.
3. To save storage. Live Wallpaper context is always persistent and never close unless user select other live wallpaper. When new texture is virtualized, it seems like jpct will save another texture in memory card, even if the same texture id but different object is saved before, CMIIW.

Hi raft,

I got this error message when converting ogre xml to bones. The 2 objects in Blender and the objects are sharing the same skeleton. What actually caused this error, since 2 objects are suppose to be different in their number of vertices and sharing the same skeleton? Did I miss anything when i separate the object into 2 with sharing skeleton?

Dive into the beautiful and breathtaking deep blue ocean with a glimpse of lively underwater sea life. The sunlight high above from crystal clear ocean surface beams through the depth of the blue ocean, together with animated coral that swing along with the sea current, and a school of fish swimming past the plankton, creates a magnificent scene that you would never forget.

Hi egon,

I tested my scene in Nexus 6 and some objects (opaque) do not show in the scene. The weirder part is, some objects (opaque) just disappear at a fixed position. Initially, I thought it's caused by other transparent objects overlapping them, but when I remove all transparent objects and render again with only opaque objects, and what I got is the objects are not render properly where they are cut off half way (see attachments). The cut off part only happen when another object is nearer to camera, overlapping it.

I checked from jpct log with debug mode, and it seems all normal. I do use custom shaders for those objects and some custom setSortOffset values. I tested on samsung s4, samsung note 10 and samsung trend plus, and they all work ok with no issue.

Do you have idea what might cause the issue?

Hi,

I have one rotation matrix retrieved from Blender with the following coordinate system:
+Z is up
+X is right
-Y is forward

How do we map/convert that matrix with the coordinate system to JPCT's coordinate system?

hi raft,

Is there any simple way to rotate the entire skeleton of an object permanently like rotateMesh() in jpct? I'm trying to map different coordination system from Blender to JPCT. Thanks.

Hi egon,

How do we apply light position final transformation for shader? I tried use Camera.transform the the light position and the final result is incorrect. I need it for uploading custom light position to shader. Thanks n look forward to ur reply.

Hi Egon,

How can we check the final vertex position after importing .obj? I wanted to map it to jpct coordination. 

Hi,

Has anyone tried camera smooth scrolling before? Something like, the camera accelerates based on velocity and slows down(decelerate) when the touch event stops.

Hi egon,

R they the same? I tried using the same method from jpct-ae and it does nt work in jpct. Plus, it shows warning like Matrix construction from matrix is not allowed in implicit GLSL version number 110

Hi Egon,

Is there anyway to get modelViewMatrix from object? I need it for multiple sub-meshes location and direction (crowd animation with hardware skinning), so I can animate the submesh by using only one object to reduce drawcall.

Hi Egon,

Does setStaticUniform upload its value to GPU every frame? If yes, is it possible if we can make it upload only once and reuse afterwards, like texture?

Hi raft,

I'm exporting bones from Blender using blender2orge and I notice the number of vertices is different. My object in Blender has 574 vertices, but in jpct getUniqueVertexCount() shows 600. Do you have any clue what's happening? I need to keep track of a few selected vertices for manipulation (for hardware skinning object instancing) but it seems like it got messed up after that.

Hi Egon,

It seems like compressing texture takes a big amount of time to process. According to log, it takes around ~2306ms just to compress all textures. It would be great if we can provide the pre-compressed texture so it would be faster to process and we can save more battery. In my case, user will check how much battery my live wallpaper will consume in the phone settings. If users open and close the live wallpaper for multiple times, the battery consumption shoots really high because of the app initialization, which they will start complaining about the app.

For reference, here's the log during texture compression (Tested on Samsung Galaxy S4 with octa cores):

Hi Egon,

I have an issue where the rendering stutters at the beginning of the onDrawFrame. I checked from log and found out it compiles shader and create buffer for VBO during rendering when object become visible. Is there any way to compile everything including shader and VBO in surfaceChanged before it starts rendering frame? I tried to call buildAllObjects() and compileAllObjects() but it seems not helping.

Here's the log during rendering:

Hi Egon,

I set my texture to mipmap and setTextureCompression(true), and it seems like the texture is pixelated and sometimes looks weird (some black area on part of the texture) for normal map, but it does not have the issue when compression is off. I'm using the shader code from http://www.jpct.net/wiki/index.php/Shaders. In addition, I tried out with the hello shader by setting all textures with etc1 compression, it looks quite different than what it is in without the compression. Is it normal that etc1 compression will lose texture quality? However, if the normal texture is compressed, it looks ok.

Hi egon,

I have this issue where the texture becoming more blur and pixelated each time the live wallpaper resumes from pause. It takes many times till the effect is obvious. The texture is in 512x512, mipmap, and compression enabled ( setTextureCompression(true) ).

Can it be the texture is compressed over and over again till it loses the quality?
