where is 1E633AF8 stored in?, [EBP-4C] ?

if so, you can filter it out by adding a code cave:

0xCodeCaveStart:
push eax
mov eax,[EBP-4C]
cmp eax,1E633AF8
je 0xDontLoadMe

pop eax
FILD DWORD PTR SS:[EBP-4C]
jmp 0xOriginalCodeAfterTheFILDCommand

0xDontLoadMe:
pop eax
jmp 0xOriginalCodeAfterTheFILDCommand
___________________________

then at 0046C27F, do a JMP 0xCodeCaveStart

if you mean that 1E633AF8 gets changed, you need to find a pointer for it, or if you can find something special related to it in the graphic loader routine.

You might be able to use ce's d3d snapshot feature to locate the code that renders a specific 3d object
Then do a code injection and use the info from the stack to decide if you call the draw operation, or just return
