What does this mean? (D3DError)

[Conchron]

I've uploaded my mod to nexus so that my tester can try it, and there is a problem. At the very beginning of the mod he puts a pair of sandals in an alcove and the game crashes.

This is the error message he gets:

[string "GameMode.lua"]:0: D3DError - Present() failed: E_INVALIDARG
stack traceback:
[C]: in function 'endRender'
[string "GameMode.lua"]: in function 'update'
[string "Grimrock.lua"]: in function 'display'
[string "Grimrock.lua"]: in main chunk

I've tried several times and I can't make it crash.

Does your tester have the most up-to-date version of the game?

Does the tester have the most up-to-date graphics drivers?

[Conchron]

He says he's up to date on both.

[msyblade]

sounds like he either A:is not aware that v1.3.6 is the newest, (most likely), or his direct 3d drivers are out of date (less likely). What scripts/connectors are on the alcove the sandals are placed in?

[Conchron]

The alcove starts a teleporter. No scripts involved.

sounds like he either A:is not aware that v1.3.6 is the newest

I'll bump him again about that part.

[Conchron]

We both have v1.3.7.

[msyblade]

Hmm, okay. Is the teleporter on the party square, ie: does the crash occur when actual teleportation is supposed to happen? Or does it activate somewhere else? Or are u using a custom particle effect?

[Conchron]

It activates somewhere else and it's not custom.

[msyblade]

d3d error doesnt fit because he wouldnt even make it far enough to place the sandal. And you cannot reproduce the error, so it is on his side.

[Dr.Disaster]

Ask for graphics card, driver version, directX version and LoG settings in use.
Also a savegame might help.

EDIT: ask what happens if he uses something else, not the sandals.
