Is it posible to make a smooth transition between two textures?

[simon_riis]

So I came across a problem where I would need to make a smooth transition from one object to another. One object penetrates the other. In this case it's a rock that sticks out of lava. but the edge where the rock meets the lava. Or rather the edge between the two objects are way too sharp. Is there a way to blur this line between objects?
Or if I merge the objects is there a way to blur tle line between two different textures on the same object?

Hi!

There is no built-in tool for this.

Based on your requirements you have to find your own solution to achieve the desire effect.

For a still image this should be no problem by using modeling tools, but for an animation it will become more complex, especially the texturing part.

Thank you for the reply.
And yeah, I thought as much.
So it will be matching the visuals in the textures that's still the only option then.
I'm wondering how they do it on open world games like Gensin impact.
They can't have a texture immage large enough to cover an entire mountain and there's so few visible edges where the texture doesn't mach.

Hi!

Some game engines provide special features and shaders to achieve such an effect.

In theory you can as shown here with a ramp and a Round Corners node ( the ramp/round corners controls the transition between 2 different objects while maintaining hard edges for the rest of the geometry)but since we don't know the specifics of your situation this solution might not be 100% good.The texturing phase can be done in a similar fashion.As @mspeer mentioned this is easier in a game engine such as Unreal, also I believe Blender might have a similar tool you can search for.

Give it a shot.
