textures blending

[bostonbrooks]

I am experimenting with 2d isometric game worlds.
I am using csfml.
I currently only have one texture for the ground which is just grass.
I have a texture that represents the area that is visible.
I have a texture that represents the area that has been explored.
I want to blend them so to give the actual texture to display.
The attachment shows the results i would like to acheive.

I would also like to blur/fade the edges of the light and dark regions.

What's the question, or even problem here?

If you are asking for suggestions about how to blend textures together, then I suggest using sf::BlendMode. Another suggestion would be to go and try something, see how it works, and if it isn't satisfactory try again. I'm not sure what else to tell you.

Thats OK, what you described is what I have been doing.
I have been doing many small experiments of what I need for my engine,
although I wouldnt expect to produce a commercial-grade product in like five years.
Working things out for myself is something i excell at,
but I was hoping some pro would swoop in and give me an easy answer.

Its annoying having to convert between textures and rendertextures.
I may decide to switch to a different media library.

Wotevs OK have nice day.
