what parameter that caused the lightness diff of same obj files as shown in screenshots

[GoogleCodeExporter]

What steps will reproduce the problem?
1. they are obj+mtl exported from different 3d tool of different versions
2. one is exported obj+mtl by 3dmax 2014
3. another is exported obj+mtl by 3dmax 2011

What is the expected output? What do you see instead?
the render effect has huge difference. 
(can be see the great contrast of lightness in attachment files) 

Please provide any additional information below.

1.wish giving some advice on what parameters and in which file (obj or mtl) 
that caused such lightness difference on one same 3d obj. 

2. obj compatibility issue is discovered that obj+mtl exported by the 3dmax2014 
 seems can not load: 
  a.color material parameters such as (changing Kd value in mtl color didn't change) 
  b.texture files such as ( while map_Kd is disabled or enalbed, doesn't show diff )

( is there any methods to detect whether obj exported is corrupted for jsc3d to 
load properly? it is caused by the corruption of which parameters in export 
setting of 3dmax) 

thank you so much

Not sure. I guess there may be somthing wrong within the mtl file. Could you 
show me the obj + mtl files exported by 3dsmax 2014 so that I can make my own 
test?

dear author , sure can send to you to file, but may i send them to u privately 
instead of uploading on the public area? otherwise it may take a bit longer 
time since i need to ask ppl re-generate two samples again through two diff 
versions of 3dmax software.

Would you mind sending those files to my gmail address?  I'll definitely keep 
your files private.
