cant think straight at moment but look at the sprite depth commands

water been the nearest depth and the ducks been the furthest ones

like
SetSpriteDepth(water, 0)
SetSpriteDepth(ducks,1)

Or something along those lines

Or is this 3D?

Same idea anyway - depths

If you want the You will need to move the water in accordance to the ducks too instead of leaving the water position the same

Those ducks looks getting bigger the nearer they are too or is that optical illusion.

Try fixobjecttoobject ducks to the water so they will always be fixed to one object (the water plane)

I have noticed this too. Objects that should logically be behind other objects just pop to the front when you move the camera. Way annoying! My solution is to increase the distance.

It's a bit of a hack, but you can pretend the water is a lot further forward using:

which fixes the rendering issue.

Aaargh! Ducks!

If you like a quick example of fixobjecttoobject to correct this theory, then please let me know - if you corrected it then well done.

Hey BlinkOK,

Pretty simple fix. Use SetObjectAlphaMask(water, 1) instead of SetObjectTransparency(water, 1).

Mine is probably more code than its worth trying to fix - Golehorn found it and is enlightened us all with the fix. Thank Golehorn.

To Golehorn, Was it yourself querying shattering objects at all? - I worked out how to shatter loading OBJ objects on another thread. I knew you was asking.

Aye, it was me. I will check it out next week. I've been working on a few other things that have bogged me down.

Thanks Golegorn, just chiming in that fix solved an issue in one of my games as well. Apparently rendering two planes that are in close range, even with using fixobjecttoobject, can cause the issue the OP mentions.
