Hi everyone !

Today, i updated a Away3D project developped a few month ago.
I was surprised with the bad render of the 3ds objects in the scene. The both side no longer work and rendering is not quality.
Look at the attached file to understand the issue.

At first my Flash project run with Away3D 4.1.5. I have updated to 4.1.6 but the problem persists.

//Setup Scene
_scene = new Scene3D();
_camera = new Camera3D();
   
_view = new View3D();
_view.antiAlias 4;
_view.scene _scene;
_view.camera _camera;
_view.mousePicker PickingType.RAYCAST_BEST_HIT;
_view.backgroundColor 0x131313;

//Mesh setting example

mesh Mesh(e.target.getChildAt(0));
mesh.pickingCollider PickingColliderType.PB_BEST_HIT;
mesh.mouseEnabled true;
mesh.shaderPickingDetails true;
mesh.geometry.convertToSeparateBuffers();

var 
w:Weld = new Weld();
w.apply(mesh);
   
var 
explode:Explode = new Explode();
explode.apply(mesh.geometry);

var 
material:TextureMaterial = new TextureMaterial(Cast.bitmapTexture(pAmfPiece.textureDiffuseCustomBitmap));
    
//
material.specularMap Cast.bitmapTexture(new SpecularMap() as Bitmap);
material.normalMap Cast.bitmapTexture(new NormalMap() as Bitmap);

material.lightPicker _lightPicker;
material.bothSides true;
material.specular 0.5;
material.gloss 0.6;
material.ambient 0.7;

mesh.material material

Thanks

Not sure what you mean by “bad render”, tho reading your code gives me a clue…

Why do you weld, meaning you explicitly ask to share as much as possible vertices, to have a smooth surface when lighted, and the next following lines, you explicitly request that all faces must be independent using explode, basically asking that the vertices normals to be parallel top face normal. Causing a per face lighted flat shading?
This also rises another one: if the meshes aren’t dynamic, as both geometry updates do cost time, wouldn’t it be a better idea to load properly crafted models? You could correct them in your editor before loading them no?
