Testing what happens if add clip(discard), remove transparency and remove color tint from default Sprite Shader.. Just wanted to see if there is big difference or not, but seems like no huge difference on PC (asus laptop, gtx970m), unless you have thousands of sprites on […]

(screenshot with Quad mesh placed on top of Plane with raycast hit.point) If you want to use Raycast hit.point to place quad on a flat surface, it will most likely create Z fighting issue.. You could add position offset by hit.point+Vector3(0,0.1f,0), Or use modified shader […]

Had a strange looking error today: Turns out it was just that the function which was called inside vertex shader, was below the vertex shader, so just moved it above the v2f vert (appdata v) and it works.. *Actually it was more complicated: This one […]

“RenderDoc is a stand-alone graphics debugging tool” Getting Started – Download standalone https://renderdoc.org/builds – Install it – Start Unity 5.3 or later (I tested with 5.4beta.f2) – Right click over the Game- or Scenewindow title, RenderDoc option should be displayed in the menu, Select it […]

Tried to test idea about tube lights (or “line light”), by using custom lighting in shader, you could sample the light several times from different positions/angles, so that it looks like the light is not just a single point. (not really working here properly yet, […]

Tried to get world position from depth texture, but it didn’t work.. then founded COMPUTE_DEPTH_01 instead, makes nice curve effect when applied to meshes (pushing the y vertices down based on depth).. although breaks a bit depending on camera rotation/position.. Shader source: https://github.com/UnityCommunity/UnityLibrary/blob/master/Shaders/Vertex/UnlitFakeCurved.shader without curve-shader: […]

  Converted this old godrays shader ( http://unitycoder.com/blog/2012/10/02/fake-godrays-shader/ ) into image effect – interesting results! (see video below)     Source codes below (Attach script to main camera) This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what […]

Finally decided to try shader matrices.. (because having issues with custom billboard shader) Doing Translate, Scale, Rotations with matrix operations seems quite simple actually! Would had been totally lost without these two links: http://www.codinglabs.net/article_world_view_projection_matrix.aspx http://www.gamedev.net/topic/610115-solved-rotation-deforming-mesh-opengl-es-20/#entry4859756 How to use the shader: – Get the source below, […]

While updating this billboard shader https://github.com/unitycoder/DoomStyleBillboardTest , had couple strange shader issues: Problem#1: Overlapping transparent area clips other object behind it (see issue#6) This one was solved by adding “ZWrite Off” to the shader, apparently something to do how transparent objects get depth sorted..(?) http://docs.unity3d.com/Manual/SL-CullAndDepth.html […]

(screenshot of modified shader properties in debug view mode) Modified built-in sprite shader so that its opaque, no color tint, and pixel snap is always on. Just to test if there are any performance benefits to use them for opaque sprite tiles, at least the […]
