Im having trouble with lava

When I try to make lava with the water tool all I get is a moving checkered board. I thought maybe it would show up once I loaded up the mod but it doesn’t it just shows the moving checkered board.

I open the water tool I make a little pool I go to edit water and select lava and boom checkered board but when I switch back to water works fine.

Can someone please help me I know not what to do or why its doing this please and thank you

You’ll have to wait for Forgotten Gods to get the official textures.

Oh you tease
