solved [Solved] Object color not like expected

[mirco]

Hi, i am new to BabylonJs. I have Imported a Mesh with BABYLON.SceneLoader.ImportMesh. Thats all works fine and super easy to learn.
But now I have a problem with the color of the imported Mesh. 
Its a tree and should be (surprise) green. But it is Black, and only the top of the tree has a little pice of green. 

As test I created some other objects around it and checked if the other objects get the expected color ( pink ). To avoid problems with light or something like that.

Maybe you have a short hint for me what I doing wrong.

Hello and welcome!!!

Thank you for your kind words. You can use the debug layer to check your material properties (see picture).

The materials of your tree are almost black

Hi thank you for your first informations. Because I have problems with seeing colors it`s not so easy for me. 

Before I submitted this post I have tested the tree with the same material like the other objects. 

Here are a playground:

in this example it looks like it have the same problem. So maybe there are some more things I make wrong ? 

Attached I have a sample how it looks like in Blender.

Can you share your blender scene? I'm pretty sure that our God of Blender (aka @gryff ;)) could help you

@Deltakosh and @mirco: Nothing to do with Blender DK   The camera and Directional Light are on opposite sides of the tree to each other.

The light is illuminating the tree mesh on the side away from the camera. The side closest to the camera  is essentially in shadow.

I moved the camera to the same side of the tree as the light - see attached image. The tree has green branches

cheers, gryff

Thanks for the support you give me, but maybe I am thinking in a wrong direction but I already looked from the other side on the object ( like the shadows fall ) by moving the camera around. 

But only the top of the tree has the "green" or "pink" color like I expect. 

I have updated the playground for faster review.

- override the green material with the pink one from the object near of it

- move the camera on the right position

- move the cane near the tree - thats what I expect to get - in the shape of a tree

I've set a white scene ambientColor and a pink material ambientColor. I'm not sure if it's exactly what you want, but give it a try

[mirco]

what I don't understand is why the cone is complete pink (on the side where the light is ) and the tree only has a little pink top, I would expect that they are looking the same because the form is "nearly" the same.

I got it : smooth shading issue http://www.babylonjs-playground.com/#16XKTO#32

l. 62 object.convertToFlatShadedMesh()

If you want control of your smooth shading : on Blender, apply a smooth shading on your object (3DView > Tool shelf > Tools tab > Shading Smooth button). Then, apply an edge split modifier, and adjust it.

If you want to set flat shaded mesh directly from Blender, check "Use Flat Shading" on Mesh BJS panel.

[mirco]

perfect, thats what I looking for

so there are two ways to get the result I "expected":

first export it correct in blender (see file attached)

or convert it in babylon with 

myMesh.convertToFlatShadedMesh();

 

Thank you all for your help
