I am trying to show water on a minimap. I either get no water plane, or only the water plane and no terrain. I am not sure why I am not getting it to display correctly. Appreciate any guidance.

No waterplane code:

x# = GetObjectX(game.player.objID)
	y# = GetObjectY(game.player.objID)
	z# = GetObjectZ(game.player.objID)
	cx# = GetCameraX( 1 )
	cy# = GetCameraY( 1 )
	cz# = GetCameraZ( 1 )
	SetCameraPosition( 1, x#, y#+12, z# )
	SetCameraRotation( 1, 0, 0, 0)
	SetCameraLookAt( 1, x#, y#, z#, 0 )
	SetRenderToImage( minimapRender, 0 )
	ClearScreen()
	SetVirtualResolution( 768, 434 )
	SetDisplayAspect( 768.0/434.0 )
	SetShadowMappingMode(0)
	// Render Objects
	DrawObject( home_grd )
	DrawObject( water_plane )
	for i = 0 to mm_objs.length
		SetObjectVisible( mm_objs[i].ID, 1 )
		DrawObject( mm_objs[i].ID )
	next i
	
	SetVirtualResolution( 100, 100 )
	SetDisplayAspect( 1366.0/768.0 )

SetCameraPosition( 1, x#, y#, z# )
	SetCameraRotation( 1, cameraanglex#, cameraangley#, cameraanglez#)
	MoveCameraLocalY( 1, player_camera_zoom#)
	MoveCameraLocalZ( 1, camera_behind_player_zoom# )
	SetCameraLookAt(1, x#, y#, z#, 0 )
	SetSpriteAngle( minimappntr_spr, GetObjectAngleY( game.player.objID )-180 )
	
	if GetSpriteExists( MiniMapspr ) = 1 then DeleteSprite( MiniMapspr )
	MiniMapspr = CreateSprite( minimapRender )
	SetSpriteAdditionalImage( MiniMapspr, mapsimg, 1 )
	SetSpriteShader( MiniMapspr, 1 )
	SetSpriteSize( MiniMapspr, 13, -1 )
	SetSpritePosition( MiniMapspr, global_right_bound-13.925, global_top_bound+2.4 )
	SetSpriteVisible( minimapcirclespr, 1 )
	SetSpriteVisible( minimappntr_spr, 1 )
	SetShadowMappingMode(2)

+ Code Snippet

	x# = GetObjectX(game.player.objID)
	y# = GetObjectY(game.player.objID)
	z# = GetObjectZ(game.player.objID)
	cx# = GetCameraX( 1 )
	cy# = GetCameraY( 1 )
	cz# = GetCameraZ( 1 )
	SetCameraPosition( 1, x#, y#+12, z# )
	SetCameraRotation( 1, 0, 0, 0)
	SetCameraLookAt( 1, x#, y#, z#, 0 )
	SetRenderToImage( minimapRender, 0 )
	ClearScreen()
	SetVirtualResolution( 768, 434 )
	SetDisplayAspect( 768.0/434.0 )
	SetShadowMappingMode(0)
	// Render Objects
	DrawObject( home_grd )
	DrawObject( water_plane )
	for i = 0 to mm_objs.length
		SetObjectVisible( mm_objs[i].ID, 1 )
		DrawObject( mm_objs[i].ID )
	next i
	
	SetVirtualResolution( 100, 100 )
	SetDisplayAspect( 1366.0/768.0 )

	SetCameraPosition( 1, x#, y#, z# )
	SetCameraRotation( 1, cameraanglex#, cameraangley#, cameraanglez#)
	MoveCameraLocalY( 1, player_camera_zoom#)
	MoveCameraLocalZ( 1, camera_behind_player_zoom# )

	SetSpriteAngle( minimappntr_spr, GetObjectAngleY( game.player.objID )-180 )

	MiniMapspr = CreateSprite( minimapRender )
	SetSpriteAdditionalImage( MiniMapspr, mapsimg, 1 )

This post has been marked by the post author as the answer.

Theres not a great deal to go on really to find out what your issue is...

It could be that your rendering 3d to a render image but your not rendering to any depth buffer so normal z ordering/occlusion just wont happen. Using -1 will allow a temporary depth buffer to be created.

Also, you seem to be recreating the sprite every time when you could just leave it and not recreate it every frame.

Your code doesnt show whats going on in the sprite shader so it could be that too.

edit: Using SetRenderToImage( minimapRender, -1 ) and drawing the water_plane after the terrain worked.

Thank you so much Bengismo! For some reason I thought the -1 created a depth image. When I read it again I am not sure why I thought that.
