Spherical Texture Projection Problem during Transform

I have a 2 K earth map, I am projecting a texture onto the sphere using the RGB texture node, when I transform my object to a different position the texture gets distorted very badly. What am I doing wrong?

Hmm, I'm not sure. Does your object have a proper UV map or are you using a projection node? If you want to share an example scene with this issue I could take a look at it here.

Sure am attaching, just using simple projection mode. Appreciate the help, just have to relink the textures to your appropriate path

Sorry, you are transforming the object at the SOP level, which means that in fact, you are deforming the mesh, so a basic spherical projection centered in the origin is not going to work. You need to transform the object at the OBJ level or add a proper UV map to the sphere and remove the projection node.

Hope it helps,

You could also add a transform node to the shader to match the sphere translation or rotation, but well, I think that a proper UV mapped sphere is the best solution to avoid problems.

Thanks a million for the help :) Now I have to learn how to do UV mapping lol :D Or I may use object level transform. Appreciate the help
