How to import an obj file containing RGB data at unity

Question

The document was translated into Google Translator.

I have an obj file containing vertex position and the RGB data for that vertex. The corresponding obj file code is as follows.

obj.file :

v 27.795225 -8.144943 -10.956295 0.647059 0.313726 0.290196

v 27.830965 -8.110074 -11.030095 0.629412 0.309804 0.290196

v 27.762598 -8.133816 -11.034611 0.647059 0.313726 0.290196

v 27.847612 -8.126033 -10.965885 0.611765 0.305882 0.290196

v 27.847620 -8.140801 -10.931058 0.631373 0.317647 0.294118

v 27.891783 -8.117332 -11.027543 0.611765 0.305882 0.290196

....

I imported the obj file to Unity, but the modelling did not have any color.

How can I apply color data to my model.

you can use the [Particle - Standard shader](https://docs.unity3d.com/Manual/shader-StandardParticleShaders.html) which has vertex color support. Or use any other [Vertex Shader](https://docs.unity3d.com/Manual/SL-VertexFragmentShaderExamples.html) — derHugo, Aug 23 '19 at 10:07

You must assign a vertex color shader to your object to see the color data. but using unity standard shader will not work reading your color information on the object.

select your material and change the shader type to vertex color shader – VectorX Aug 30 '19 at 19:44
