Irrlicht Engine

Thanks for the patch.

I have a small question unrelating to the topic (I just don't want to create a separate thread for it): is there some support of GLSL > 1.2 version currently in Irrlicht? I would like to try to use in and out specifiers in the vertex and fragment shaders as I need in passing a ...

Isn't that what I wrote after the "Ow... or maybe I do get it ..."?

I'm not quite sure what would happen. I searched a bit around the web and found answers from "gpu will just clip it, no problem" to "this is badly defined in OpenGL" to "might depend on the graphic card what happens". If you ...

As I already said before, the screen mesh objects doesn't move around their scenes as well as their cameras. Only their view port rectangles shift happens if the coords of the object were changed. Ok, I show my code snippets and explain what they do.

I have a HUD scene class which exists per a mesh ...

Maybe you are missing some aspect ratio changes? Your first image has 15/8 your second has something like 2 times 7.5/8 (with the images you posted here, I guess real ones are likely not exactly the same).

The camera always renders the full height of your given field of view (ICameraSceneNode ...

I'm making some API for Minetest engine allowing to render and handle meshes in the screen space of the player camera. When some new mesh is added, it creates a separate scene manager for it (smgr->createNewSceneManager), adds to there the own camera and the mesh node itself. When rendering all ...

Thanks. I read thoroughly all materials types documented in EMaterialTypes.h file since the doc in the engine itself is more actual than that one which the website says. I really didn't find any suitable type that would just combine two textures (what is very wonderful as other materials can combine ...

I have a mesh scene node (mirror) with two materials. The second one contains two texture layers. In the first layer I add a render target texture (created using IVideoDriver::addRenderTargetTexture) in which the camera renders from the position of the mirror node and from that direction where the ...

This will be probably a bit offtopic, but I am interested in knowing reasons of disintegrating of the Irrlicht development team. The single active developer and the forum member so far is CuteAlien. The lastest feature release (1.8.0) is more than ten years old. The lastest bugfix release is also ...

The red light amount is the same as the green one in my scene. The actual problem was the red light has the green and blue components null, so in the result of the blending the light color with the scene color, the total color gets semitransparent with the red tint. I could fix that by calculating ...

I've come up with how to solve this issue finally, only partially, because now although the lamps look like opaque, but their rays became very faint. I caulculate the alpha as a ratio of the current fragment's luminance and the original lamp color luminance:


float luminance = dot(color*255.0 ...

Do you mean so? Always have alpha = 1.0 independing on the mixed alpha?
In any case that doesn't change anything.

I try to combine in the shader which renders the screen quad the total rays texture with the base texture. The first one contains all simple rendered cube light sources emitting godrays (algorithm based on this implementation: https://lokeshsharma97.wordpress.com/2017/08/04/god-rays-opengl/ the only ...

Thanks! Setting EMT_TRANSPARENT_ALPHA_CHANNEL for the base shader material is the only thing that solved the problem.

Sorry for very frequent asking here, but it really doesn't work for an obscure reason although it really should do. I bound an own shader to my material which belongs to a mesh scene node and enabled the blend operation EBO_ADD since this material is intended to be transparent (that shader ...

Now works too to my wonder. The single reason which I can find is I initialized core::array wrong (when I added ITextures to there, I used direct [] operator, now I added it by push_back()), because actually my current code and the non-working code before are absolutely identical except that thing ...
