Object seems to be black

Hi @arkeon and @iri ...when i add an object through mesh it looks blackish on the screen...when marker finds it ..it hardly visible means it is black in color.....


I am using model which is given in the asset....i.e. alligator          assets\models\library\Kingdom_Animalia\Alligator....still i find an issue while making it visible on the screen

Re: Object seems to be black

Hello,
maybe it as a bad material, what if you change the material settings in the material editor ?

what if you convert the bmp texture file into jpg and change it in the material editor ?

also the aligator object is very big, did you scaled it to make it smaller ?

Re: Object seems to be black

Hy Arkeon
I have a problem with an airplane model, do it in Maya 2014, export it as "obj" to 3ds Max 2013 to animate it, then export it as "Scene Ogre" with "Easy Ogre Exporter (latest version)" for OS3D, and the model I'm all black. Perform a test importing the "obj" in OS3D and the model appears with the texture in place, with a texture problem in the part that holds the propeller, it is inverted.
Now optimize the textures reducing their weight to the maximum, but they remain the same, all the textures are in PNG format.
Perform the same process with a wing like Ogre scene but still in black.
I hope you can support me with this problem.

Re: Object seems to be black

Hello,
edit the material and uncheck two sided, transparent and rejection if any

The Easy Ogre max exporter manage png texture with transparency. so if you use a png texture he will enable transparency on material.
easiest method is to use jpg for textures without transparency, this also optim the scene a bit

Re: Object seems to be black

Hi Arkeon

I followed your instructions and the problem of the textures was solved. Maya's "backface culling" was deactivated.

Thanks for your support,
